  [InstCombine] Pull vector reverse through intrinsics (#146384)

This is the intrinsic version of #146349, and handles fabs as well as
other intrinsics.

It's largely a copy of InstCombinerImpl::foldShuffledIntrinsicOperands
but a bit simpler since we don't need to find a common mask.

Creating a separate function seems to be cleaner than trying to shoehorn
it into the existing one.
