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 d9a1faaa9cff6eab069ea8e5cd7862d0ae48e231 (#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.
Remove the `..` from the body, only a few invocations used it and it's
inconsistent with rust syntax.
Use `;` instead of `,` between consts. As the Rust syntax gods inteded.
This removes the `custom` format functionality as its only user was
trivially migrated to using a normal format.
If a new use case for a custom formatting impl pops up, you can add it
back.

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 🙂

fs: Fix#50619 (again) and add a regression test
Bug #50619 was fixed by adding an end_of_stream flag in #50630.
Unfortunately, that fix only applied to the readdir_r() path. When I
switched Linux to use readdir() in #92778, I inadvertently reintroduced
the bug on that platform. Other platforms that had always used
readdir() were presumably never fixed.
This patch enables end_of_stream for all platforms, and adds a
Linux-specific regression test that should hopefully prevent the bug
from being reintroduced again.
