This change has a 0.3% compile-time regression (https://llvm-compile-time-tracker.com/compare.php?from=0c55889d809027136048a0d144209a2bc282e7fc&to=71f3169e1baeff262583b35ef88f8fb6df7be85e&stat=instructions) and a 0.3% max-rss regression (https://llvm-compile-time-tracker.com/compare.php?from=0c55889d809027136048a0d144209a2bc282e7fc&to=71f3169e1baeff262583b35ef88f8fb6df7be85e&stat=max-rss).

Is that expected? The diff looks pretty harmless to me.
