Rust Compiler Performance Triage

A relatively quiet week with improvements largely outweighing regressions. On the regressions side, doc performance has worsened somewhat significantly most likely introduced by adding more docs to blanket impls. On the improvement side, LLVM 14 allowed for an optimization the significantly improves codegen performance.

Triage done by @rylev. Revision range: a240ccd..1204400

3 Regressions, 2 Improvements, 7 Mixed; 3 of them in rollups 38 comparisons made in total
