Switch to only using aarch64 runners (implying we are now
cross-compiling) and stop running tests. In the future, we could
enable (some?) tests via Rosetta 2.
Free disk space on Windows 2025 runners
I've managed to reduce the time deletion takes by:
- Using powershell, which is generally faster for filesystem operations than msys2
- Performing deletions concurrently then waiting for them all to complete
It still takes 2-10 mins but that's not too bad.
Instead of making this a build parameter, pass the SCRIPT as an
environment variable.
To this purpose, normalize on always referring to a script in
`/scripts`.
For i686-gnu-nopt-2 I had to create a separate script, because
Docker seems to be really terrible at command line argument
parsing, so it's not possible to pass an environment variable that
contains whitespace.
Add an aarch64-msvc build running on ARM64 Windows
Resurrecting rust-lang/rust#126341
Per <https://github.com/rust-lang/rfcs/pull/3817> we intend to promote `aarch64-pc-windows-msvc` to Tier 1. As part of that work, we are adding a pre-merge CI job to validate that changes do not break this target.
Additionally, for consistency, the `dist-aarch64-msvc` job will also be run on Arm64 Windows runners.

Rename `mingw-*` CI jobs to `pr-*`
The name `mingw` confuses people because these CI jobs now do much more than just cross-compile to mingw.
This is basically a find/replace. I chose the name `pr-` because it's job is to do general PR checks,
Switch `x86_64-msvc-{1,2}` back to Windows Server 2025 images
New Windows Server 2025 images have been released (**20250527.1.0**). New images appear to not exhibit the lack-of-disk-space problem as tracked by rust-lang/rust#141022, and the new runner image's storage capacity appears to be configured correctly.
Windows Server 2025 image version **20250527.1.0** release notes: <https://github.com/actions/runner-images/releases/tag/win25%2F20250527.1>.

Miri CI: test aarch64-apple-darwin in PRs instead of the x86_64 target
The aarch64 target is more important, and also this ensures we cover all main architectures (x86_64, i686, aarch64) in PR CI.
Remove RUSTC_RETRY_LINKER_ON_SEGFAULT hack
It looks like this was added in rust-lang/rust#40422 6 years ago because of issues with the MacOS linker. MacOS got a new linker in the meantime, so that should probably be resolved now. Hopefully.

CI: Add cargo tests to aarch64-apple-darwin
This adds running of cargo's tests to the aarch64-apple-darwin job. The reason for this is that tier-1 targets are ostensibly supposed to run tests for host tools, but we are not doing that here. We do have fairly good coverage in Cargo's CI, but we don't cover the beta or stable branches here. I think it would be good to have a fallback here.
I think this should only add about 7 minutes of CI time, but I have not measured it. The current job is about 1.5 hours.
In summary of the tier-1 targets:
| Target | rust-lang/cargo | rust-lang/rust |
|--------|-----------------|----------------|
| aarch64-apple-darwin | stable/nightly | ❌ (this PR) |
| aarch64-unknown-linux-gnu | stable/nightly | ✓ |
| x86_64-apple-darwin | nightly | ❌ |
| x86_64-pc-windows-gnu | nightly | ❌ |
| x86_64-pc-windows-msvc | stable | ✓ |
| x86_64-unknown-linux-gnu | stable/beta/nightly | ✓ |
| i686-pc-windows-msvc | ❌ | ❌ |
| i686-unknown-linux-gnu | ❌ | ❌ |
