Summary: This change led to moderate relevant regressions 😿 in compiler performance.

• Moderate regression in instruction counts (up to 2.0% on incr-patched: println builds of regression-31157)

If you disagree with this performance assessment, please file an issue in rust-lang/rustc-perf.

Next Steps: If you can justify the regressions found in this perf run, please indicate this with @rustbot label: +perf-regression-triaged along with sufficient written justification. If you cannot justify the regressions please open an issue or create a new PR that fixes the regressions, add a comment linking to the newly created issue or PR, and then add the perf-regression-triaged label to this PR.

Visiting for weekly performance triage

Only regression-31157 opt regressed, by 1.6-2.0%.

I don't think its worth investing effort trying to figure out the root cause of this limited regression.

(I will note that regression #31157 was itself put in to catch a performance regression with respect to time and RAM, but that regression was more like 1,882% in time and 10x in space.)
