Previously, we were too conservative and `x.field = 4` was treated as a "use" of `x`.
Also, run RustFmt on the clashing_extern_fn test case and update stderrs.

Add partition_point Add partition_point in C++. Although existing binary_search in rust does not suitable when the slice has multiple hits, this function returns exact point of partition. The definition of this function is very clear and able to accept general matter, therefore you can easily get index which you want like lower/upper_bound. rust-lang/rfcs#2184
…leywiser Const prop: erase all block-only locals at the end of every block I messed up this erasure in rust-lang#73656 (comment). I think it is too fragile to have the previous scheme. Let's benchmark the new scheme and see what happens. r? @wesleywiser cc @felix91gr
…ons, r=oli-obk Make liveness more precise for assignments to fields Previously, we were too conservative and `x.field = 4` was treated as a "use" of `x`. Now it neither kills `x` (since other fields of `x` may still be live) nor marks it as live. cc @jonas-schievink, who ran into this problem.
…r=oli-obk Add some `const_compare_raw_pointers`-related regression tests Closes rust-lang#71381 Closes rust-lang#71382 Closes rust-lang#71611 Closes rust-lang#72352 r? @oli-obk, the author of rust-lang#73398
Forward Hash::write_iN to Hash::write_uN The `Hasher::write_iN()` methods should forward to `Hasher::write_uN()`, because some Hasher implementations implement only the `write_uN()` variants, with the expectation that `write_iN()` will use the same implementation. Most notably, this is the case for the [FxHasher](https://github.com/rust-lang/rustc-hash/blob/5e09ea0a1c7ab7e4f9e27771f5a0e5a36c58d1bb/src/lib.rs#L111) used by rustc itself. This used to be the case previously, but was broken in rust-lang#59982. As the PR description makes no mention of this particular change, I assume it was unintentional. In a local test, this mitigates the regression from rust-lang#73526 on at least one test-case (cc @cuviper), because we're no longer at the mercy of `FxHasher::write()` getting inlined to get reasonable performance.
Rename two `Resolver` traits `trait Resolver` -> `trait ResolverExpand` for the resolver interface available from expansion. `trait Resolver` -> `trait ResolverAstLowering` for the resolver interface available from AST lowering. Addresses rust-lang#73587 (comment)
…eclarations, r=petrochenkov Rename clashing_extern_decl to clashing_extern_declarations. Rename clashing_extern_decl to clashing_extern_declarations to bring in-line with lint naming conventions. Fixes rust-lang#73802. r? @petrochenkov
Fix docstring typo

@cuviper oh, shoot, i'm sorry, didn't notice that. We can do a perf run directly through try perhaps? |
I'm not sure how to isolate one PR for perf after the fact, but it looks like a small change anyway. |

@cuviper oh good point lol |
