Add long error docs for `E0460` and `E0457`
Final docs for errors in #61137 that have UI tests, my next PRs will also add these tests.

Realistic `Path::as_mut_os_str` doctest
With "Implement DerefMut for PathBuf" (#105018) now merged, it's
possible to exercise `Path::as_mut_os_str` (#105002) without going
through `into_boxed_path`.
Use a more efficient `Once` on platforms without threads
The current implementation uses an atomic queue and spins rather than panicking when calling `call_once` recursively. Since concurrency is not supported on platforms like WASM, `Once` can be implemented much more efficiently using just a single non-atomic state variable.
Re-enable ThinLTO for rustc on `x86_64-apple-darwin`
ThinLTO was disabled on x64 mac in https://github.com/rust-lang/rust/pull/105646 because of the https://github.com/rust-lang/rust/issues/105637 regression.
It was later discovered that the issue was present on other targets as well, as the mac revert was already landing. The linux/win reverts, however, did not land before the root cause was identified.
https://github.com/rust-lang/rust/pull/105800 fixed the underlying issue in `-Zdylib-lto` handling, and the x64 msvc and linux targets are now fixed, ICEs are using the correct `rustc_driver` panic hook.
This PR re-enables ThinLTO on mac for improved perf now that the issue should be fixed everywhere.

Revert "Introduce lowering_arena to avoid creating AST nodes on the fly"
This reverts commit d9a1faaa9c (#101499).
This was originally part of #101345 which has now been closed as a different approach is taken now.

print argument name in arg mismatch if possible
A bit more contextual than just `/* value */`, at least when the argument is named something related to its context.
The UI test cases are... not super convincing, but also they're minimized tests.
Fix `x setup -h -v` should work
r? `@jyn514`
I have to convert profile to path and back in order to remove special-casing in bootstrap. I also check for `dry_run` so that `config.toml` and/ or `.git/hooks/pre-push` will not be created if `--dry-run` is specified.
Please help me see if this is ok, thanks alot!
Run `x test tidy` sooner in mingw-check
It takes less time to run than the other tests and is more likely to fail. `expand-yaml-anchors` is still run first to make sure the CI files are internally consistent.
Note that changing to `--stage 0` doesn't actually do anything since bootstrap tools are always built with the bootstrap compiler, this just makes it less confusing.

Migrate rustc_mir_build diagnostics
Rebases https://github.com/rust-lang/rust/pull/100854
~~The remaining issue is how to better resolve 72bea68af4~~
~~The diagnostic macros seems to generate a broken diagnostic, and I couldn't figure out how to manually format the fluent message, so I hardcoded the format string for now. I'd like pointers to a better fix for this.~~
Also, I'm not 100% sure I didn't mess up a rebase somewhere 🙂
