Log:
Revert "revert r179735, it has no testcases, and doesn't really make sense."
This un-reverts r179735 and reverts commit r180574.
This fixes assertion failures for me locally and should fix the failures
on Windows reported widely on llvm-dev. We should check if the bots
caught this and if so why not.
