[Nikita Popov via llvm-commits]

https://github.com/nikic created https://github.com/llvm/llvm-project/pull/75050

This recovers more of the max-rss regression introduced by https://reviews.llvm.org/D157657.

Per http://llvm-compile-time-tracker.com/compare.php?from=dd32d26a37e22a3bce15ed8c21145b17ff5e1401&to=b4d4aba0dfbbe405f4da3494575434710f4ec9b9&stat=max-rss&linkStats=on this is an about 1.2% max-rss improvement for the LTO link stage with debuginfo.
