This dropped off my radar and I realized that I fixed the cause of the crash which was the reason for the latest revert in 60b852092c98dbdc6248d60109d90ae6f8ad841c <https://reviews.llvm.org/rG60b852092c98dbdc6248d60109d90ae6f8ad841c>. But I never recommitted the patch. I am planning on doing so tomorrow.

Compile-time impact seems much less than when it was committed originally now:
