This is an alternative to carrying a revert of the offending changeset, since the bug doesn't show hope of a fix anytime soon, or maybe ever. This way we don't have to keep rebasing the patch as we pick up new clangs, and developers don't have to remember to apply the patch when building a local compiler.
