Move the dist-aarch64-linux CI job to an aarch64 runner instead of
cross-compiling it from an x86 one. This will make it possible to
perform optimisations such as LTO, PGO and BOLT later on.

Promote powerpc64le-unknown-linux-musl to tier 2 with host tools
MCP: https://github.com/rust-lang/compiler-team/issues/803
I'm using crosstool-ng for building a toolchain because GCC 9 from `musl-toolchain.sh` has float ABI issues (?) and can't compile LLVM, and writing a crosstool-ng config for a target feels less hacky than yet another target specific shell script. I also defined a kernel version, since there wasn't one specified before. If a lower version is desired, just let me know. I also tried to match the rust configure args with the loongarch64 musl tier 2 target.
The resulting compiler works fine, built with `DEPLOY=1 ./src/ci/docker/run.sh dist-powerpc64le-linux` and tested on Alpine Linux in a VM and on a bare metal POWER8 machine:

CI: move `dist-arm-linux` to an ARM runner
First, I want to test whether we could actually move this to a free runner, vs moving to the 8-core ARM runner.

Replace black with ruff in `tidy`
`ruff` can both lint and format Python code (in fact, it should be a mostly drop-in replacement for `black` in terms of formatting), so it's not needed to use `black` anymore. This PR removes `black` and replaces it with `ruff`, to get rid of one Python dependency, and also to make Python formatting faster (although that's a small thing).
If we decide to merge this, we'll need to "reformat the world" - `ruff` is not perfectly compatible with `black`, and it also looks like `black` was actually ignoring some files before. I tried it locally (`./x test tidy --extra-checks=py:fmt --bless`) and it also reformatted some code in subtrees (e.g. `clippy` or `rustc_codegen_gcc`) - I'm not sure how to handle that.

use `--exact` on `--skip` to avoid unintended substring matches
Without the `--exact` flag, using `--skip tests/rustdoc` can unintentionally skip other tests that match as substrings such as `rustdoc-gui`, `rustdoc-js`, etc.
For debugging, run: `./x.py --stage 2 test rustdoc-ui --skip tests/rustdoc` and `./x.py --stage 2 test rustdoc-ui --skip tests/rustdoc -- --exact`

Run the full stage 2 `run-make` test suite in `x86_64-gnu-debug`
Run the full `run-make` test suite in the `x86_64-gnu-debug` CI job. This is currently the *only* CI job where `//@ needs-force-clang-based-test` will be satisfied, so some `run-make` tests will literally never be run otherwise. Before this PR, the CI job only ran `run-make` tests which contains the substring `clang` in its test name, which is both (1) a footgun because it's very easy to forget and (2) it masks tests that would otherwise fail (even failing to compile) because the test is skipped if doesn't have a `clang` in its test name.
With the environment of `x86_64-gnu-debug`, two `run-make` tests failed before this PR:
1. `tests/run-make/issue-84395-lto-embed-bitcode/rmake.rs`: this was broken for a long time because `objcopy` in llvm bin tools was renamed to `llvm-objcopy`. This test was converted into a rmake.rs test, rather straight forward.
2. `tests/run-make/cross-lang-lto-riscv-abi/rmake.rs`: this was broken for a long time and never worked. The old version inspected human-readable output of `llvm-readobj --file-header` looking for substring `EF_RISCV_FLOAT_ABI_DOUBLE`, but the human-readable output will only contain something like `Flags: 0x5, RVC, double-float ABI`, hence it will never match. This test was fixed by instead using the `object` crate to actually decode the ELF headers looking for the specific `e_flags` based on reading the RISCV ELF psABI docs.
This PR is best reviewed commit-by-commit, two commits setup the support library for functionality and two commits are for each of the failing `run-make` tests.
I had to bump the `x86_64-gnu-debug` job to be ran with a runner with larger disk space.
Part of #132034.

Adds a new CI job which checks that the compiler builds with
`--enable-debug` and tests that `needs-force-clang-based-tests` pass
(where cross-language LTO is tested).

Full stage 2 build + run-make with full debug info seems to overwhelm
the standard 4c runner's storage capacity.

(ci) Update macOS Xcode to 15
This updates the macOS builders to Xcode 15. The aarch64 images will be removing Xcode 14 and 16 very soon (https://github.com/actions/runner-images/issues/10703), so we will need to make the switch to continue operating. The linked issue also documents GitHub's new policy for how they will be updating Xcode in the future. Also worth being aware of is the future plans for x86 runners documented in https://github.com/actions/runner-images/issues/9255 and https://github.com/actions/runner-images/issues/10686, which will impact our future upgrade behaviors.
I decided to also update the Xcode in the x86_64 runners, even though they are not being removed. It felt better to me to have all macOS runners on the same (major) version of Xcode. However, note that the x86_64 runners do not have the latest version of 15 (15.4), so I left them at 15.2 (which is currently the default Xcode of the runner).
Xcode 15 was previously causing problems (see #121058) which seem to be resolved now. `@bjorn3` fixed the `invalid r_symbolnum` issue with cranelift. The issue with clang failing to link seems to be fixed, possibly by the update of the pre-built LLVM from 14 to llvm 15 in https://github.com/rust-lang/rust/pull/124850, or an update in our source version of LLVM. I have run some try builds and at least LLVM seems to build (I did not run any tests).
Closes #121058

ci: add a runner for vanilla LLVM 19
Ubuntu 24.10 has `llvm-19` packages that we can start testing with.
The `Dockerfile` is otherwise the same as the `llvm-18` runner.
