Support `download-ci-llvm` on NixOS
In particular, the CI built `libLLVM-*.so` needs to have `libz.so`
RPATHed so that binaries like `llvm-config` work at all.

./x.py clippy: allow the most noisy lints
This silences the following clippy lints in ./x.py clippy:
many_single_char_names (there are a lot of warnings caused by stdarch)
collapsible_if (can reduce readability)
type_complexity
missing_safety_doc (there are almost 3K warnings issued)
too_many_arguments
needless_lifetimes (people want 'tcx lifetimes etc)
wrong_self_convention (warns about from_..(), to_..(), into_..().. fns that do or do not take self by reference.
Just for clarification; this only changes the output of `x.py clippy` inside the rustc repo and does not change anything about clippy or how `cargo clippy` is run on peoples crates.
Builder: Warn if test file does not exist
Running `./x.py test` with a file that does not exists (but where the path belongs to a test suite) silently ignores the missing file and runs the whole test suite. This PR prints a warning to reduce the potential surprise factor.
Closes#80621
Don't use `self.date` unconditionally for `program_out_of_date()`
This avoids unnecessary cache invalidations for programs not affected by
the stage0 version (which is everything except the stage0 compiler
itself).
The redundant invalidations weren't noticed until now because they only
showed up on stage0 bumps, at which point people are used to rebuilding
everything anyway. I noticed it in https://github.com/rust-lang/rust/pull/79540
because I wasn't adding `self.date` to the stamp file (because I didn't realize it was necessary). Rather than
adding self.date I thought it was better to remove it from the cache key.

Enable ASan, TSan, UBSan for aarch64-apple-darwin.
I confirmed ASan, TSan, UBSan all work for me locally with `clang` on my new Macbook Air.

Only produce .xz tarballs on CI
This PR adds a `./configure` option to choose which tarball compression formats to produce, and changes our CI configuration to only produce `.xz` tarballs. The release process will then recompress everything into `.gz` when producing a release.
This will drastically reduce our storage costs for CI artifacts, as we'd stop storing the same data twice. **Stable, beta and nightly releases will not be affected by this at all.**
Before landing this we'll need to increase the VM size of our release process, to recompress everything in a reasonable amount of time.

Don't give an error when creating a file for the first time
Previously, `os.remove` would always give a FileNotFound error the first
time you called it, causing bootstrap to make unnecessary copies. This
now only calls `remove()` if the file exists, avoiding the unnecessary
error.
This is a pretty small cleanup but I think it's useful. Taken from https://github.com/rust-lang/rust/pull/79540.
Add llvm-libunwind change to bootstrap CHANGELOG
From #77703.
This doesn't need a `changelog-seen` version bump because the old values aren't accepted anymore, meaning anyone who was using this had to change it already.

bootstrap: put the component name in the tarball temp dir path
This should not matter right now, but if we ever parallelize rustbuild this will avoid tarball contents being merged together.
