[PATCH] D62787: [X86] Add the vector integer min/max instructions to isAssociativeAndCommutative.

[Craig Topper via Phabricator via llvm-commits]

craig.topper updated this revision to Diff 203026.
craig.topper added a comment.

-Add the SQ and UQ instructions.
-Fix the MIN list which I thought I just copied from the MAX list and search and replaced.
-Show test diffs in machine-combiner-int-vec.ll which now tests min/max
