[PATCH] D41436: [X86][AVX512] Enable variable shuffle combining by default on AVX512 targets

[Zvi Rackover via Phabricator via llvm-commits]

zvi added a comment.

Still trying to get hold of a KNL expert that will answer whether KNL should be included. Can we for now conservatively assume no and exclude KNL from this patch just so this patch can make progress? I want to follow-up on updating the AVX2 tests with FastVariableShuffle configurations.
