[PATCH] D60214: [DAGCombiner] move splat-shuffle after binop with splat constant

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

My only concern is the width reduction on the BROADCAST - as these could regress AVX512 memory folding - but then again that isn't working great in many cases as it is (due to existing SimplifyDemanded calla, shuffle combining etc.) - @craig.topper what do you reckon?
