[PATCH] D103274: [X86] Split FeatureFastVariableShuffle tuning into Lane-Crossing and Per-Lane variants

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

I'm happy with this but I do think we should always enable variable shuffles (both types) on all AVX512 targets as well (and maybe land that first to simplify this patch) - @pengfei @craig.topper what do you think?
