[PATCH] D96405: [DAGCombiner] Reduce Shuffle_Vector Nodes Count

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

I'm not sure how useful this really is - we already have something very similar later in the function that uses the MergeInnerShuffle lambda - maybe we're just missing an edge case there? But as @craig.topper said we need to be careful about performing this in later legalization stages.
