[PATCH] D149742: [SLP]Improve isGatherShuffledEntry by trying per-register shuffle.

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

Why are we doing this in SLP and not TTI getShuffleCost? It looks like TTI should be doing a better job of recognizing how it should split the shuffle mask and determine the shuffle kinds per split?
