- Refactors the Emscripten target spec to share code with other wasm
targets.
- Replaces the incorrect wasm32 C call ABI with the old asmjs
version, which is correct for both wasm32 and JS.
- Updates the varargs ABI used by Emscripten and deletes the old one.
- Removes the obsolete wasm32-experimental-emscripten target.
- Temporarily makes Emscripten targets use panic=abort by default
because supporting unwinding will require an LLVM patch.

Make all alt builders produce parallel-enabled compilers
We're not quite ready to ship parallel compilers by default, but the alt
builders are not used too much (in theory), so we believe that shipping
a possibly-broken compiler there is not too problematic.

Shouldn't have an effect on produced artifacts and otherwise is causing
issues where `-Zsave-analysis` is passed during tests but fails
compilation.

azure: Convert Windows installations scripts to `bash`
Looks like `script`, which uses `cmd.exe`, doesn't have fail-fast
behavior and if a leading command fails the script doesn't actually fail
so long as the last command succeeds. We instead want the opposite
behavior where if any step fails the whole script fails.
I don't really know `cmd.exe` that well, nor powershell, so I've opted
to move everything to `bash` which should be a good common denominator
amongst all platforms to work with. Additionally I know that `set -e`
works to cause scripts to fail fast.
Closes #64551

Note that some scripts remain as `script` since they don't appear to
work in` bash`. I'm not really sure why but I reorganized them slightly
to have the "meaty command" run at the end.

This commit changes our CI to use two separate IAM users to
authenticate with AWS:
* ci--rust-lang--rust--sccache: has access to the rust-lang-ci-sccache2
S3 bucket and its credentials are available during the whole build.
* ci--rust-lang--rust--upload: has access to the rust-lang-ci2 S3 bucket
and its credentials are available just during the upload step.
The new tokens are available in the `prod-credentials` library.

azure: Disable more LLVM/debug assertions in
This commit disables LLVM/debug assertions in our 5 slowest builders:
* i686-gnu
* i686-gnu-nopt
* i686-msvc-1
* i686-msvc-2
* x86_64-msvc-cargo
This is reducing the amount of test coverage for LLVM/debug assertions,
but we're just unfortunately running out of time on CI too many times.
Some test builds have shown that i686-gnu drops nearly an hour of CI
time by disabling these two assertions. Perhaps when we eventually get
4-core machines we can reenable these, but for now turn them off and
hook them up to the tracking issue at #59637 which will ideally be
repurposes to tracking all of these.

GitHub only allows people explicitly listed as collaborators on the
repository or who commented on the issue/PR to be assignees, failing to
create the issue if non-assignable people are assigned.
This adds an extra check on CI to make sure all the people listed as
tool maintainers can be assigned to toolstate issues. The check won't be
executed on PR builds due to the lack of a valid token.

ci: move linkcheck from mingw-2 to mingw-1
Running UI tests now takes a huge amount of time on mingw builders
(between 40 and 50 minutes), with mingw-1 builders taking even an hour
less to finish than mingw-2. This PR moves linkcheck from mingw-2 to
mingw-1, removing between 10 and 20 minutes of runtime on the -2
builders.

ci: add a check for clock drift
Recently we encountered multiple spurious failures where the crates.io
certificate was reported as expired, even though it's currently due to
expire in a few months. This adds some code to our CI to check for clock
drifts, to possibly find the cause or rule out a bad VM clock.

Currently mirrors are stored in the rust-lang-ci2 S3 bucket along with
CI toolchains. This is problematic for multiple reasons:
- CI IAM credentials are allowed to both edit and delete those files.
A malicious user gaining access to those credentials would be able to
change our mirrored dependencies, possibly backdooring the compiler.
- Contents of the rust-lang-ci2 bucket are disposable except for the
mirrors' content. When we implement backups for S3 buckets we'd have
to replicate just that part of the bucket, complicating the backup
logic and increasing the chance of mistakes. A standalone bucket will
be way easier to backup.
This commit switches our CI to use the new rust-lang-ci-mirrors bucket.

Added support for armv7-unknown-linux-gnueabi/musleabi
Fixes #63101
Some things that are not done and I hope someone can help me with:
* During the ci build of `armv7-unknown-linux-gnueabi` `openssl` must be built (to build cargo) but `openssl` does not yet support this target. This feels slightly like a chicken-and-egg problem, any feedback is welcome.
* Should I add any tests for any of these targets?

Support for the targets in the compiler and std build in the CI.

ci: fix toolstate not pushing data for Linux
A recent commit modified toolstate to only push updated data when the `TOOLSTATE_PUBLISH` environment variable is present. This worked fine on Windows but failed on Linux, since Linux jobs run inside Docker containers and the variable wasn't forwarded inside it.
This changes the Docker startup code to set the `TOOLSTATE_PUBLISH` enviornment variable inside the container if it's present outside.

ci: download awscli from our mirror
This fixes multiple network issues we had when downloading awscli from PyPI on Azure Pipelines by vendoring awscli itself and its dependencies in our S3 bucket. Instructions on how to update the cache are present at the top of `src/ci/install-awscli.sh`.

ci: gate toolstate repo pushes on the TOOLSTATE_PUBLISH envvar
This PR fixes toolstate failing to push on the LinuxTools PR builder by gating the pushes on the new `TOOLSTATE_PUBLISH` environment variable, which is set on prod credentials but not on the PR ones. The old code checked whether the access token was set, but that doesn't work due to an Azure quirk.
For a bit of background, secret environment variables are not available by default, but each step needs to explicitly declare which secret vars to load:
```yaml
- bash: echo foo
env:
SECRET_VAR: $(SECRET_VAR)
```
This works fine when the variable is present but when it's missing, instead of setting `SECRET_VAR` to an empty string or just not setting it at all, Azure Pipelines puts the literal `$(SECRET_VAR)` as the content, which completly breaks the old check we had. I tried almost every thing to make this work in a sensible way, and the only conclusion I reached is to set the variable at the top level with the runtime expression evaluation syntax, which sets the variable to an empty string if missing:
```yaml
# At the top:
variables:
- name: MAYBE_SECRET_VAR
value: $[ variables.MAYBE_SECRET_VAR ]
# In the step:
- bash: echo foo
env:
SECRET_VAR: $(MAYBE_SECRET_VAR)
```
While that *could've worked* it was ugly and messy, so I just opted to add yet another non-secret variable.

Unfortunately due to an Azure quirk the TOOLSTATE_REPO_ACCESS_TOKEN is
not suitable to gate whether to push new commits to the repo, as if it's
not defined on the Azure side it will actually be set to the literal
`$(TOOLSTATE_REPO_ACCESS_TOKEN)`, which screws everything up.
This instead adds another, non-secret environment variable to gate
publishing: TOOLSTATE_PUBLISH. As non-secret environment variables
behave correctly this fixes the issue.

Require a value for configure --debuginfo-level
In `configure.py`, using the `o` function creates an enable/disable
boolean setting, and writes `true` or `false` in `config.toml`. However,
rustbuild is expecting to parse a `u32` debuginfo level. We can change
to the `v` function to have the options require a value.

Add riscv32i-unknown-none-elf target
This target is likely to be useful for constrained FPGA soft-cores, such as picorv32 and HeavyX.
