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

[Igor Breger via llvm-commits]

igorb added a comment.

I think we need this patch for correctness in case we got this intrinsic with const index in back-end ( for example if  InstCombiner doesn't run , -O0 compilation) .
