--- Comment #4 from Sanjay Patel <spatel+llvm at rotateright.com> ---
Resolving as fixed: we use vblendv now on the test in the problem description,
and we use vblendv for the cases in comment 1 where it makes sense.
The AVX1 256-bit cases use andn/and/or, and that's likely the best they can do
in that situation.
