Auto merge of #79680 - Nadrieril:fix-regression-79284, r=jonas-schievink
Fix perf regression caused by #79284 https://github.com/rust-lang/rust/pull/79284 only moved code around but this changed inlining and caused a large perf regression. This fixes it for me, though I'm less confident than usual because the regression was not observable with my usual (i.e. incremental) compilation settings. r? `@Mark-Simulacrum`
