--- Comment #1 from Sanjay Patel <spatel+llvm at rotateright.com> ---
Thanks for the bug report. This was caused by:
https://reviews.llvm.org/rL324014

And fixed with:
https://reviews.llvm.org/rL324252

I added a test based on this bug report with:
https://reviews.llvm.org/rL324266

There was (and might still be) a different problem with the original commit, so
we may end up reverting it, but we'll keep the tests either way.
