I suspect you'll want to land this, and then @hans will want to roll clang while you're on vacation, and there is some risk that the larger object files will cause problems and he'll need to revert it.


+1 A flag would be great, and we can enable it by default for Chromium's win/lld builds to get coverage without potentially disrupting developers using link.exe.
