[Demikhovsky, Elena via llvm-commits]

Usage of masked gather and scatter are limited by target. Currently it is supported on AVX-512 only.

Subject: Re: [PATCH] D15690: Gather and Scatter intrinsics in the Loop Vectorizer

In the latest patch I see no code to address non-default address spaces problem mentioned in the review. I don't see a test for this either. I assume this code introduces another one bug to loop-vectorize. It should be addressed at least by limiting the scope of the optimization to default address space pointers for now.
