--- Comment #5 from Sanjay Patel <spatel+llvm at rotateright.com> ---
The patch was reverted at:
https://reviews.llvm.org/rL345780

Tests added:
https://reviews.llvm.org/rL345831

And the retry:
https://reviews.llvm.org/rL345832

Also, I filed bug 39518 because there's a missed canonicalization/optimization
opportunity I noticed based on this pattern.
