Migrate `run-make/pgo-branch-weights` to `rmake`
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
This is a scary one and I expect things to break. Set as draft, because this isn't ready.
- [x] There is this comment here, which suggests the test is excluded from the testing process due to a platform specific issue? I can't see anything here that would cause this test to not run...
> // FIXME(mati865): MinGW GCC miscompiles compiler-rt profiling library but with Clang it works
// properly. Since we only have GCC on the CI ignore the test for now."
EDIT: This is specific to Windows-gnu.
- [x] The Makefile has this line:
```
ifneq (,$(findstring x86,$(TARGET)))
COMMON_FLAGS=-Clink-args=-fuse-ld=gold
```
I honestly can't tell whether this is checking if the target IS x86, or IS NOT. EDIT: It's checking if it IS x86.
- [x] I don't know why the Makefile was trying to pass an argument directly in the Makefile instead of setting that "aaaaaaaaaaaa2bbbbbbbbbbbb2bbbbbbbbbbbbbbbbcc" input as a variable in the Rust program directly. I changed that, let me know if that was wrong.
- [x] Trying to rewrite `cat "$(TMPDIR)/interesting.ll" | "$(LLVM_FILECHECK)" filecheck-patterns.txt` resulted in some butchery. For starters, in `tools.mk`, LLVM_FILECHECK corrects its own backslashes on Windows distributions, but there is no further mention of it, so I assume this is a preset environment variable... but is it really? Then, the command itself uses a Standard Input and a passed input file as an argument simultaneously, according to the [documentation](https://llvm.org/docs/CommandGuide/FileCheck.html#synopsis).

Add TODO comment to unsafe env modification
Addresses https://github.com/rust-lang/rust/pull/124636#issuecomment-2132119534.
I think that the diff display regresses a little, because it's no longer showing the `+` to show where the `unsafe {}` is added. I think it's still fine.

Add no_std Xtensa targets support
Adds no_std Xtensa targets. This enables using Rust on ESP32, ESP32-S2 and ESP32-S3 chips.
Tier 3 policy:
> 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.)
`@MabezDev` and I (`@SergioGasquez)` will maintain the targets.
> 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.
The target triple is consistent with other targets.
> 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.
We follow the same naming convention as other targets.
> 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 does not introduce any legal issues.
> The target must not introduce license incompatibilities.
There are no license incompatibilities
> Anything added to the Rust repository must be under the standard Rust license (MIT OR Apache-2.0).
Everything added is under that licenses
> 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.
Requirements are not changed for any other target.
> 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.
The linker used by the targets is the GCC linker from the GCC toolchain cross-compiled for Xtensa. GNU GPL.
> "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.
No such terms exist for this target
> 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.
Understood
> 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 target already implements core.
> 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.
Here is how to build for the target https://docs.esp-rs.org/book/installation/riscv-and-xtensa.html and it also covers how to run binaries on the target.
> 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.
Understood
> 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.
No other targets should be affected
> Tier 3 targets must be able to produce assembly using at least one of rustc's supported backends from any host target.
It can produce assembly, but it requires a custom LLVM with Xtensa support (https://github.com/espressif/llvm-project/). The patches are trying to be upstreamed (https://github.com/espressif/llvm-project/issues/4)

Add {{target}} substitution to compiletest
In ferrocene we have ui tests testing the cli interface of the compiler, one of which tests the `--target` flag. To be able to run this on all targets we require a way to specify a valid target in the `compile-flags` directive that is target independent, as otherwise we can only run the test against the one target we choose to supply in the flags. See https://github.com/ferrocene/ferrocene/blob/383cbc80f4e85859a4055f121f15dac329908346/tests/ui/ferrocene/compiler-arguments/target/target.rs
We figured the project might be able to make use of this substitution as well in the future.

Weekly `cargo update`
Replaces #125562
`r-efi` needs to be bumped in two places.
The `icu4x` dependencies also added a SPDX license identifer, so remove the license checking exception and add `Unicode-3.0` to the list.

bootstrap: vendor crates required by opt-dist to collect profiles
These are the default package set required by opt-dist to correctly work,
hence for people wanting to build a production grade of rustc in a
sandboxed / air-gapped environment, these need to be vendored.
The size of `rustc-src-nightly.tar.xz` before and after this change:
* Before: 298M
* After: 323M (+8%)
Size change might or might not be a concern.
See the previous discussion: https://github.com/rust-lang/rust/pull/125166#issuecomment-2113626468
Previous efforts on making:
* https://github.com/rust-lang/rust/pull/125125
* https://github.com/rust-lang/rust/pull/125166
---
Note that extra works still need to be done to make it fully vendored.
* The current pinned rustc-perf uses `tempfile::Tempdir` as the working
directory when collecting profiles from some of these packages.
This "tmp" working directory usage make it impossible for Cargo to pick
up the correct vendor sources setting in `.cargo/config.toml` bundled
in the rustc-src tarball. [^1]
* opt-dist verifies the final built rustc against a subset of rustc test
suite. However it rolls out its own `config.toml` without setting
`vendor = true`, and that results in `./vendor/` directory removed.

`ring` is included because it is an optional dependency of `hyper`,
which is a training data in rustc-pref for optimized build.
The license of it is generally `ISC AND MIT AND OpenSSL`,
though the `package.license` field is not set.
See https://github.com/briansmith/ring/issues/902
`git+https://github.com/rust-lang/team` git source is from
`rust_team_data`, which is used by `site` in src/tools/rustc-perf.
This doesn't really a part of the compiler,
so doesn't really affect the bootstrapping process.
See https://github.com/rust-lang/rustc-perf/pull/1914.

Winnow private method candidates instead of assuming any candidate of the right name will apply
partially reverts https://github.com/rust-lang/rust/pull/60721
My original motivation was just to avoid the `delay_span_bug` (by attempting to thread the `ErrorGuaranteed` through to here). But then I realized that the error message is wrong. It refers to the `Foo<A>::foo` instead of `Foo<B>::foo`. This is almost invisible, because both functions are the same, but on different lines, so `-Zui-testing` makes it so the test is the same no matter which of these two functions is referenced.
But there's a much more obvious bug: If `Foo<B>` does not have a `foo` method at all, but `Foo<A>` has a private `foo` method, then we'll refer to that one. This has now been fixed, and we report a normal `method not found` error.
The way this is done is by creating a list of all possible private functions (just like we create a list of the public functions that can actually be called), and then winnowing it by analyzing where bounds and `Self` types to see if any of the found methods can actually apply (again, just like with the list of public functions).
I wonder if there is room for doing the same thing with unstable functions instead of running all of method resolution twice.
r? ``@compiler-errors`` for method resolution stuff

Rewrite `suspicious-library`, `resolve-rename` and `incr-prev-body-beyond-eof` `run-make` tests in `rmake.rs` format
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
Some oddly specific ignore flags in `incr-prev-body-beyond-eof`:
```rs
// ignore-none
// ignore-nvptx64-nvidia-cuda
```
it could be interesting to run a try job, but it seems there is no nvidia-cuda in the CI settings (`jobs.yml`).
