Rust Compiler Performance Triage

A good week, despite a few PRs that pnkfelix opted not to mark as triaged. In particular, a broad set of primary benchmarks improved, due to improvements to resolve (PR #118188) and a one-pass rewrite of exhaustiveness (PR #117611).

Triage done by @pnkfelix. Revision range: 4f3da903..df0295f0

1 Regressions, 5 Improvements, 5 Mixed; 2 of them in rollups 84 artifact comparisons made in total
