[PATCH] D43593: [X86] Add a custom legalization for (i16 (bitcast v16i1)) and (i32 (bitcast v32i1)) without AVX512 to prevent scalarization

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

So there's no way to extend combineBitcastvxi1 to split wider types like we do for AVX/PSUBUS/PMADDWD ?
