### Rust Compiler Performance Triage

<!-- Perf results go here -->
Mostly positive week. Most of the improvements come from a revert of a regression from a few weeks ago, but we also get nice wins from re-using Sized fast-path, coming from Sized hierarchy implementation work.

Triage done by **@panstromek**.
Revision range: [15f58c46..8f2819b0](https://perf.rust-lang.org/?start=15f58c46da79399961a09db0c650a2f90f442e6b&end=8f2819b0e3428d0aee05fa60e91e0211c2aea053&absolute=false&stat=instructions%3Au)

**Summary**:

| (instructions:u) | mean | range | count |
|:----------------------------------:|:-----:|:---------------:|:-----:|
| Regressions ❌ <br /> (primary) | 1.3% | [0.4%, 2.1%] | 7 |
| Regressions ❌ <br /> (secondary) | - | - | 0 |
| Improvements ✅ <br /> (primary) | -1.0% | [-12.9%, -0.1%] | 144 |
