[PATCH] D27825: [AVX-512][InstCombine] Teach InstCombine to converted masked vpermv intrinsics into shufflevector instructions

Simon, you mean turning other shuffles into VPERMV/VPERMV3? This patch would tend to prevent usage of VPERMV/VPERMV3 in favor of other shuffles. But may breaking masking so to recover masking we'd need to turn those other shuffles in to VPERMV/VPERMV3.
