We should symlink /usr/include/x86_64-linux-gnu/asm for the host
triple, rather than /usr/include/asm-generic, which is used in the
implementation for asm for specific triple, but shouldn't be used
by itself.

The zicsr feature has been split off from the base ISA. A newer
binutils version is required to recognize it.

CI: do not hide error logs in a group
This PR avoids creating a GHA group at the very end of a CI workflow when some failure has happened. Before, when a failure has happened, its GHA group was not closed, however the clock drift check function would create a new group, which would actually close the group containing the error log, thus making errors hidden by default, which is not ideal.
See discussion here: https://rust-lang.zulipchat.com/#narrow/stream/326414-t-infra.2Fbootstrap/topic/GHA.20groups.20being.20closed.20on.20failures

fix(ci): Ensure idempotence of user creation
Previously, re-running `run.sh` in the same container would fail at the useradd step, because the user already exists. Instead, change that step to "create if not exists" semantics to ease interactive debugging of CI failures.

Currently, having a dirty `obj/` directory is sufficient to abort CI
tests. This results in errors like the following:
```
...
== end clock drift check ==
sccache: Starting the server...
configure: error: Existing 'config.toml' detected.
== clock drift check ==
...
```
This is subtle and doesn't give a good idea as to what causes the issue.
With this patch, the error becomes more prominent and a resolution is
suggested:
```
== end clock drift check ==
sccache: Starting the server...
configure: ERROR: Existing 'config.toml' detected. Exiting
Is objdir '/home/tmgross/projects/rust/obj' clean?
== clock drift check ==
```

WASI threads, implementation of wasm32-wasi-preview1-threads target
This PR adds a target proposed in https://github.com/rust-lang/compiler-team/issues/574 by `@abrown` and implementation of `std::thread::spawn` for the target `wasm32-wasi-preview1-threads`
### Tier 3 Target Policy
As tier 3 targets, the new targets are required to adhere to [the tier 3 target policy](https://doc.rust-lang.org/nightly/rustc/target-tier-policy.html#tier-3-target-policy) requirements. This section quotes each requirement in entirety and describes how they are met.
> - A tier 3 target must have a designated developer or developers (the "target maintainers") on record to be CCed when issues arise regarding the target. (The mechanism to track and CC such developers may evolve over time.)
See [src/doc/rustc/src/platform-support/wasm32-wasi-preview1-threads.md](https://github.com/rust-lang/rust/pull/112922/files#diff-a48ee9d94f13e12be24eadd08eb47b479c153c340eeea4ef22276d876dfd4f3e).
> - Targets must use naming consistent with any existing targets; for instance, a target for the same CPU or OS as an existing Rust target should use the same name for that CPU or OS. Targets should normally use the same names and naming conventions as used elsewhere in the broader ecosystem beyond Rust (such as in other toolchains), unless they have a very good reason to diverge. Changing the name of a target can be highly disruptive, especially once the target reaches a higher tier, so getting the name right is important even for a tier 3 target.
> - Target names should not introduce undue confusion or ambiguity unless absolutely necessary to maintain ecosystem compatibility. For example, if the name of the target makes people extremely likely to form incorrect beliefs about what it targets, the name should be changed or augmented to disambiguate it.
If possible, use only letters, numbers, dashes and underscores for the name. Periods (.) are known to cause issues in Cargo.
The target is using the same name for $ARCH=wasm32 and $OS=wasi as existing Rust targets. The suffix `preview1` introduced to accurately set expectations because eventually this target will be deprecated and follows [MCP 607](https://github.com/rust-lang/compiler-team/issues/607). The suffix `threads` indicates that it’s an extension that enables threads to the existing target and it follows [MCP 574](https://github.com/rust-lang/compiler-team/issues/574) which describes the rationale behind introducing a separate target.
> - Tier 3 targets may have unusual requirements to build or use, but must not create legal issues or impose onerous legal terms for the Rust project or for Rust developers or users.
> - The target must not introduce license incompatibilities.
> - Anything added to the Rust repository must be under the standard Rust license (MIT OR Apache-2.0).
> - The target must not cause the Rust tools or libraries built for any other host (even when supporting cross-compilation to the target) to depend on any new dependency less permissive than the Rust licensing policy. This applies whether the dependency is a Rust crate that would require adding new license exceptions (as specified by the tidy tool in the rust-lang/rust repository), or whether the dependency is a native library or binary. In other words, the introduction of the target must not cause a user installing or running a version of Rust or the Rust tools to be subject to any new license requirements.
> - Compiling, linking, and emitting functional binaries, libraries, or other code for the target (whether hosted on the target itself or cross-compiling from another target) must not depend on proprietary (non-FOSS) libraries. Host tools built for the target itself may depend on the ordinary runtime libraries supplied by the platform and commonly used by other applications built for the target, but those libraries must not be required for code generation for the target; cross-compilation to the target must not require such libraries at all. For instance, rustc built for the target may depend on a common proprietary C runtime library or console output library, but must not depend on a proprietary code generation library or code optimization library. Rust's license permits such combinations, but the Rust project has no interest in maintaining such combinations within the scope of Rust itself, even at tier 3.
> - "onerous" here is an intentionally subjective term. At a minimum, "onerous" legal/licensing terms include but are not limited to: non-disclosure requirements, non-compete requirements, contributor license agreements (CLAs) or equivalent, "non-commercial"/"research-only"/etc terms, requirements conditional on the employer or employment of any particular Rust developers, revocable terms, any requirements that create liability for the Rust project or its developers or users, or any requirements that adversely affect the livelihood or prospects of the Rust project or its developers or users.
This PR does not introduce any new dependency.
The new target doesn’t support building host tools.
> Tier 3 targets should attempt to implement as much of the standard libraries as possible and appropriate (core for most targets, alloc for targets that can support dynamic memory allocation, std for targets with an operating system or equivalent layer of system-provided functionality), but may leave some code unimplemented (either unavailable or stubbed out as appropriate), whether because the target makes it impossible to implement or challenging to implement. The authors of pull requests are not obligated to avoid calling any portions of the standard library on the basis of a tier 3 target not implementing those portions.
The full standard library is available for this target as it’s an extension to an existing target that has already supported it.
> The target must provide documentation for the Rust community explaining how to build for the target, using cross-compilation if possible. If the target supports running binaries, or running tests (even if they do not pass), the documentation must explain how to run such binaries or tests for the target, using emulation if possible or dedicated hardware if necessary.
Only manual test running is supported at the moment with some tweaks in the test runner codebase. For build and running tests see [src/doc/rustc/src/platform-support/wasm32-wasi-preview1-threads.md](https://github.com/rust-lang/rust/pull/112922/files#diff-a48ee9d94f13e12be24eadd08eb47b479c153c340eeea4ef22276d876dfd4f3e).
> - Neither this policy nor any decisions made regarding targets shall create any binding agreement or estoppel by any party. If any member of an approving Rust team serves as one of the maintainers of a target, or has any legal or employment requirement (explicit or implicit) that might affect their decisions regarding a target, they must recuse themselves from any approval decisions regarding the target's tier status, though they may otherwise participate in discussions.
> - This requirement does not prevent part or all of this policy from being cited in an explicit contract or work agreement (e.g. to implement or maintain support for a target). This requirement exists to ensure that a developer or team responsible for reviewing and approving a target does not face any legal threats or obligations that would prevent them from freely exercising their judgment in such approval, even if such judgment involves subjective matters or goes beyond the letter of these requirements.
> - Tier 3 targets must not impose burden on the authors of pull requests, or other developers in the community, to maintain the target. In particular, do not post comments (automated or manual) on a PR that derail or suggest a block on the PR based on a tier 3 target. Do not send automated messages or notifications (via any medium, including via `@)` to a PR author or others involved with a PR regarding a tier 3 target, unless they have opted into such messages.
> - Backlinks such as those generated by the issue/PR tracker when linking to an issue or PR are not considered a violation of this policy, within reason. However, such messages (even on a separate repository) must not generate notifications to anyone involved with a PR who has not requested such notifications.
> - Patches adding or updating tier 3 targets must not break any existing tier 2 or tier 1 target, and must not knowingly break another tier 3 target without approval of either the compiler team or the maintainers of the other tier 3 target.
> - In particular, this may come up when working on closely related targets, such as variations of the same architecture with different features. Avoid introducing unconditional uses of features that another variation of the target may not have; use conditional compilation or runtime detection, as appropriate, to let each target run code supported by that target.
I acknowledge these requirements and intend to ensure they are met.

aarch64-msvc: remove CI hack for bad Windows SDK version
This removes hack which manually replaced windows sdk version, as it looks like useless now, as CI uses newer version: https://github.com/rust-lang-ci/rust/actions/runs/5596259246/jobs/10233070602#step:24:929
`C:\Program Files (x86)\Windows Kits\10\include\10.0.22621.0\ucrt\corecrt_io.h` (look at version)
related https://github.com/rust-lang/rust/issues/88796
It's nice to have some way to assert bad version, but i don't see anything except checking env https://github.com/rust-lang/cc-rs/pull/646

Previously, the `id -u $LOCAL_USER_ID` check would succeed, because there was already a user mapped to the $LOCAL_USER_ID with a different name.
Looking up the entry in the database by name, however, correctly makes the `useradd` operation idempotent. An alternative fix would be to avoid duplicating an already-existing-ID, however that would require either probing for an available ID or identifying where LOCAL_USER_ID is being set and changing it to better match the ubuntu base image, neither of which is a one-line change.

ci: update ubuntu:20.04 builders to 22.04
This is mostly just maintenance to avoid bitrotting, but 22.04 also updates to cmake 3.22, so they don't need the manual builds from #113714 anymore.

This is consistent with what we had from `arm-linux-gnueabihf-gcc` in

CI: build CMake 3.20 to support LLVM 17
LLVM 17 will require CMake at least 3.20, so we have to go back to building our own CMake on the Linux x64 dist builder.

This also adds a dynamic check that we don't emit nested groups, since GHA currently doesn't support them.

Add Tests for native wasm exceptions
### Motivation
In PR #111322, I added support for native WASM exceptions. I was asked by ``@davidtwco`` to add some tests for it in a follow up PR, which seems like a very good idea.
This PR adds three tests for this feature:
* codegen: ensure the correct LLVM instructions are used
* assembly: ensure the correct WASM instructions are used
* run-make: ensure the exception handling works; the WASM code is run using a small nodejs script which demonstrates the exception handling
### Complications
There are a few changes beside adding the tests, which were necessary
* Tests for the wasm32-unknown-unknown target are (as far as I know) only run on `test-various`. Its docker image uses nodejs-15, which is very old. Experimental support for wasm-exceptions was added in nodejs16. In nodejs 18.12 (LTS), they are stable.
- --> increase nodejs to 18.12 in `test-various`
* codegen/assembly tests are not performed for the wasm32-unknown-unknown target yet
- --> add those to `test-various` as well
Due to the last point, some tests are run which have not run before (assembly+codegen tests for wasm32-unknown-unknown). I added `// ignore wasm32-bare` for those which failed
### Local testing
I run all tests locally using both `test-various` and `wasm32`. As far as I know, none of the other systems run any test for wasm32 targets.

CI: include workflow name in concurrency group
Currently, this won't change anything, because we only have one relevant workflow (`CI`), but for future proofing we should probably include the workflow name in the concurrency group.

CI: merge msvc cargo and tools jobs
The `x86_64-msvc-cargo` and `x86_64-msvc-tools` jobs both run for ~1 hour, but most of that time is actually spent in building LLVM and `rustc`, so I want to try merging them.

Use `llvm-config` instead of `download-ci-llvm` in PGO script
This should avoid CI breakage when the LLVM stamp is updated, and also it will avoid an unnecessary LLVM download from CI.

CI: do not cancel concurrent builds on the same branch
Do not cancel concurrent builds on the same branch (outside of PRs).
Instead, only cancel them if the builds have the same commit SHA.
From the [documentation](https://docs.github.com/en/actions/learn-github-actions/contexts#github-context):
> The commit SHA that triggered the workflow. The value of this commit SHA depends on the event that triggered the workflow.
