[PATCH] D41323: [X86][SSE] Add cpu feature for aggressive combining to variable shuffles

[Zvi Rackover via Phabricator via llvm-commits]

zvi added a comment.

Here's the full list of tests that are affected by setting AllowVariableMask for Depth=2. I think that we should have the full list covered with the new configuration.
I would be happy to assist with the work involved.
