Perform deeper compiletest path normalization for `$TEST_BUILD_DIR` to account for compare-mode/debugger cases, and normalize long type file filename hashes
Fixes #136510.
### Summary
- Whereas previously `$TEST_BUILD_DIR` is a normalization of `/path/to/build/test/<test_suite_name>/`, we now more deeply normalize. `$TEST_BUILD_DIR` now becomes a normalization of `/path/to/build/test/<test_suite_name>/<subdirs>/$name.$revision.$compare_mode.$debugger/` to normalize away path name differences when `--compare-mode` and/or `--debugger` are specified.
- We also centralize the normalization of long type name hashes
cf. https://github.com/rust-lang/rust/pull/136328#discussion_r1936760908.
### Review advice
- Best reviewed commit-by-commit.
- Split into 3 commits:
- **Commit 1**: compiletest changes to have `$TEST_BUILD_DIR` more deeply normalize.
- **Commit 2**: remove per-test hacks for long type path hash normalizations, and rebless tests *specifically* affected by that.
- **Commit 3**: rebless other tests that were changed as a side-effect of deeper `$TEST_BUILD_DIR` normalizations.
**Commit 2** is created via first finding tests that try to perform long type file hash normalizations on an ad hoc, per-test basis:
```
rg --no-ignore -l --no-ignore -F -e "long-type" tests/ui/**/*.rs
```

Retire the legacy `Makefile`-based `run-make` test infra
The final piece of [porting run-make tests to use Rust #121876](https://github.com/rust-lang/rust/issues/121876).
Closes #121876.
Closes #40713.
Closes #81791 (no longer using `wc`).
Closes #56475 (no longer a problem in current form of that test; we don't ignore the test on `aarch64-unknown-linux-gnu`).
### Summary
This PR removes the legacy `Makefile`-based `run-make` test infra which has served us well over the years. The legacy infra is no longer needed since we ported all of `Makefile`-based `run-make` tests to the new `rmake.rs` infra.
Additionally, this PR:
- Removes `tests/run-make/tools.mk` since no more `Makefile`-based tests remain.
- Updates `tests/run-make/README.md` and rustc-dev-guide docs to remove mention about `Makefile`-based `run-make` tests
- Update test suite requirements in rustc-dev-guide on Windows to no longer need MSYS2 (they should also now run successfully on native Windows MSVC).
- Update `triagebot.toml` to stop backlinking to #121876.
**Thanks to everyone who helped in this effort to modernize the `run-make` test infra and test suite!**

Add `dist::Gcc` build step
This PR adds a `dist:Gcc` bootstrap step to distribute a prebuilt `libgccjit.so` from CI on x64 Linux.
With primed sccache, the build takes ~4 minutes on CI, and produces a 50 MiB archive.
I want to land this before adding something akin to `[gcc] download-ci-gcc = true`, to already have the artifacts available on CI, to make it easier to setup the download merge-base logic.

Compile run-make-support and run-make tests with the bootstrap compiler
It does not seem necessary to have to recompile run-make-support on changes to the local compiler/stdlib. This PR simplifies the implementation of a few tools, then switches rms to stage0 and also makes the handling of environment variables in run-make tests simpler.
Best reviewed commit-by-commit. I can split it into multiple PRs if you want.
Also tested that `COMPILETEST_FORCE_STAGE0=1 ./x test tests/run-make --stage 0` still works. Incredibly, it looks like it even passes more tests than on `master` :laughing:

Postprocess bootstrap metrics into GitHub job summary
This PR adds a postprocessing step to each CI job that writes the build and test step bootstrap metrics into [GitHub job summary](https://github.blog/news-insights/product-news/supercharging-github-actions-with-job-summaries/).

Support raw-dylib link kind on ELF
raw-dylib is a link kind that allows rustc to link against a library without having any library files present.
This currently only exists on Windows. rustc will take all the symbols from raw-dylib link blocks and put them in an import library, where they can then be resolved by the linker.
While import libraries don't exist on ELF, it would still be convenient to have this same functionality. Not having the libraries present at build-time can be convenient for several reasons, especially cross-compilation. With raw-dylib, code linking against a library can be cross-compiled without needing to have these libraries available on the build machine. If the libc crate makes use of this, it would allow cross-compilation without having any libc available on the build machine. This is not yet possible with this implementation, at least against libc's like glibc that use symbol versioning. The raw-dylib kind could be extended with support for symbol versioning in the future.
This implementation is very experimental and I have not tested it very well. I have tested it for a toy example and the lz4-sys crate, where it was able to successfully link a binary despite not having a corresponding library at build-time.
I was inspired by Björn's comments in https://internals.rust-lang.org/t/bundle-zig-cc-in-rustup-by-default/22096/27

Always allow rustdoc-json tests to contain long lines
The rustdoc-json test syntax often requires very long lines, so the checks for long lines aren't really useful.
`@aDotInTheVoid` told me she'd like this and
r? jieyouxu
you're gonna tell me that the implementation is terrible. at least the performance seems reasonable: 2.5s after and 2.5s before.

A few cleanups after the removal of `cfg(not(parallel))`
I noticed a few small things that are no longer needed after the removal of `cfg(not(parallel))` in #132282.
One of the later changes adjusts several imports, so viewing the changes individually is recommended.

I left a specialized error message that should help users that hit this
in the wild (for example, because they use it in their CI).

This is to make test stderr insensitive to compare-mode / debugger that
changes the test build dir output name.
Previously, this normalized paths up to test-suite-specific build root,
e.g. `/path/to/build/test/ui/`. Now, this normalizes up to test-specific
build root, e.g.
`/path/to/build/test/ui/subdir/$name.$revision.$mode.$debugger/`.

Implement `#[cfg]` in `where` clauses
This PR implements #115590, which supports `#[cfg]` attributes in `where` clauses.
The biggest change is, that it adds `AttrsVec` and `NodeId` to the `ast::WherePredicate` and `HirId` to the `hir::WherePredicate`.

With the removal of `cfg(parallel_compiler)`, these are always shared
references and `std::sync::OnceLock`.

completion-ref-matching
|
|
For consistency with `rustc_lexer::TokenKind::Bang`, and because other
`ast::TokenKind` variants generally have syntactic names instead of
semantic names (e.g. `Star` and `DotDot` instead of `Mul` and `Range`).
|
|
`BinOpToken` is badly named, because it only covers the assignable
binary ops and excludes comparisons and `&&`/`||`. Its use in
`ast::TokenKind` does allow a small amount of code sharing, but it's a
clumsy factoring.
This commit removes `ast::TokenKind::BinOp{,Eq}`, replacing each one
with 10 individual variants. This makes `ast::TokenKind` more similar to
`rustc_lexer::TokenKind`, which has individual variants for all
operators.
Although the number of lines of code increases, the number of chars
decreases due to the frequent use of shorter names like `token::Plus`
instead of `token::BinOp(BinOpToken::Plus)`.
