[PATCH] D21148: [X86][SSE] Added support for combining target shuffles to (V)PSHUFD/VPERMILPD/VPERMILPS immediate permute

[Simon Pilgrim via llvm-commits]

RKSimon updated this revision to Diff 61211.
RKSimon added a comment.

Rebased. Added an extra check that forces use of 256-bit float/double unary shuffles on AVX1 targets (since it doesn't have any 256-bit integer shuffles).
