--- Comment #3 from Sanjay Patel <spatel+llvm at rotateright.com> ---
Trying a more comprehensive IR fix with:
https://reviews.llvm.org/D52059 ( https://reviews.llvm.org/rL342324 )
and
https://reviews.llvm.org/rL342806

This has the potential of regressing code if the boolean compare vector source
gets lost (we can't re-form the blendv), so I'm watching for complaints, but
marking this as fixed for now.
