Visiting for weekly performance triage.

This had no primary regressions; for secondary, it caused a 1.2% regression on externs incr-full, in debug and opt variants. It also caused a 0.5% regression on tt-muncher (opt full).

I don't see any reason why the PRs in this rollup would have anything to do with that regression.
