Enable MIR inlining
Continuation of https://github.com/rust-lang/rust/pull/82280 by `@wesleywiser.`
#82280 has shown nice compile time wins could be obtained by enabling MIR inlining.
Most of the issues in https://github.com/rust-lang/rust/issues/81567 are now fixed,
except the interaction with polymorphization which is worked around specifically.
I believe we can proceed with enabling MIR inlining in the near future
(preferably just after beta branching, in case we discover new issues).
Steps before merging:
- [x] figure out the interaction with polymorphization;
- [x] figure out how miri should deal with extern types;
- [x] silence the extra arithmetic overflow warnings;
- [x] remove the codegen fulfilment ICE;
- [x] remove the type normalization ICEs while compiling nalgebra;
- [ ] tweak the inlining threshold.

Previously, this printed the debugging options, not the lint options,
and only handled `-Whelp`, not `-A/-D/-F`.
This also fixes a few other misc issues:
- Fix `// check-stdout` for UI tests; previously it only worked for run-fail and compile-fail tests
- Add lint headers for tool lints, not just builtin lints
- Remove duplicate run-make test
interpret: make a comment less scary
This slipped past my review: "has no meaning" could be read as "is undefined behavior". That is certainly not what we mean so be more clear.
cleanup mir visitor for `rustc::pass_by_value`
by changing `& $($mutability)?` to `$(& $mutability)?`
I also did some formatting changes because I started doing them for the visit methods I changed and then couldn't get myself to stop xx, I hope that's still fairly easy to review.
bootstrap: illumos platform flags for split-debuginfo
Bootstrap currently provides `-Zunstable-options` for platforms
when using split debuginfo - this commit adds it for the illumos
target too.
When moving this to rustbuild, I introduced a bug: if you had the file already downloaded, but
deleted the sysroot for whatever reason, rustbuil would fail to unpack the cached tarball.
This only affects people if they have a cached tarball, which is probably why we haven't seen an issue yet -
wiping `build/cache` would work around the issue, or just not deleting `build/$TARGET/stage2`.
Closes#96189Closes#96189
Everything is `Clone, Debug, PartialEq, Eq, Hash, Serialize, Deserialize`
except `Crate` and `Item` which arn't `Hash`, as they have `HashMap`'s.
See linked issue for reasoning.
rustdoc: fix 98690 Panic if invalid path for -Z persist-doctests
Closes#98690 for rustdoc panic
I changed this to do eprintln and orderly panic instead of unwrap doing unhandled panic
~/gg/rust/build/x86_64-unknown-linux-gnu/stage2/bin/rustdoc --test -Z unstable-options --persist-doctests /tmp/foobar main.rs
Couldn't create directory for doctest executables: Permission denied (os error 13)
Improve some inference diagnostics
- Properly point out point location where "type must be known at this point", or else omit the note if it's not associated with a useful span.
- Fix up some type ambiguity diagnostics, errors shouldn't say "cannot infer type for reference `&'a ()`" when the given type has no inference variables.
Use CSS variables to handle theming
This is the start for our simplification of theming. Considering how big the diff quickly becomes, I think it's better to do it in multiple parts.
(The 3 first commits come from https://github.com/rust-lang/rust/pull/98297 so once it's merged, they'll disappear).
Normally they shouldn't be any UI changes. You can check it [here](https://rustdoc.crud.net/imperio/css-simplification/doc/foo/index.html).

Allow macOS to build LLVM as shared library
Inspired by how [homebrew](https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/llvm.rb) builds and distributes llvm, here we manually create a symlink with a versioned dylib path to make `llvm-config` work properly. Note, the resulting `rustc` executable and `librustc_driver-<hash>.dylib` still links to the un-versioned `libLLVM.dylib` as expected when distributed in the final output. I have confirmed this by checking `otool -L` on both binaries.
After the change, enabling `llvm.link-shared` and `llvm.thin-lto` will be possible on macOS.
