[PATCH] D20897: [AVX512/AVX][Intrinsics] Fix Variable Bit Shift Right Arithmetic intrinsic lowering.

[Simon Pilgrim via llvm-commits]

RKSimon added a comment.

I just think we're better off handling simplification of intrinsics as early as possible - in this case in InstCombiner::visitCallInst instead of waiting until lowering.

Also, should we be adding constant folding (or other optimizations) to LowerINTRINSIC_WO_CHAIN ? I understood that is for cleanup + canonicalization only.
