[PATCH] D89105: [X86] Support Intel avxvnni

[Craig Topper via Phabricator via llvm-commits]

craig.topper added a comment.

We also need to add avxvnni versions of the patterns from this commit along with appropriate testing. Maybe just split the 128/256 bit out of avx512vnni.ll and into a separate test with multiple RUN lines. That should all be done in a separate patch.
