[PATCH] D76508: [VectorUtils] move x86's scaleShuffleMask to generic VectorUtils

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

This shouldn't be endian specific - DAGCombiner::visitVECTOR_SHUFFLE already does SHUFFLE(BITCAST,UNDEF)->BITCAST(SHUFFLE) with its own almost-identical version of ScaleShuffleMask.
