### Rust Compiler Performance Triage

<!-- Perf results go here -->
We saw improvements to a large swath of benchmarks with the querification of
MonoItem collection (PR #132566). There were also some PRs where we are willing
to pay a compile-time cost for expected runtime benefit (PR #132870, PR #120370),
or pay a small cost in the single-threaded case in exchange for a big parallel
compilation win (PR #124780).

Triage done by **@pnkfelix**.
Revision range: [d4822c2d..7d40450b](https://perf.rust-lang.org/?start=d4822c2d84c242cc7403118b50c571464f38ef8f&end=7d40450b2df92bdc9dec414b30cf5f7a5979a92e&absolute=false&stat=instructions%3Au)
