[PATCH] D27811: [CostModel][X86] Add support for broadcast shuffle costs

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon updated this revision to Diff 82260.
RKSimon added a comment.

Added ShuffleVectorInst::isSplat as suggested.

Regarding the refactor to use TTI::ShuffleKind instead of ISD::SHUFFLE_VECTOR in the LUTs - is everyone happy with me to commit this to trunk and I'll then update this patch with the new scheme?
