[PATCH] D55780: [X86] Create PSUBUS from (add (umax X, C), -C)

[Sanjay Patel via Phabricator via llvm-commits]

spatel added a comment.

1. Preliminary: add the tests with baseline trunk checks.
2. We should have test coverage for v8i16, v16i16, and v32i8.
3. This doesn't solve the addusb part of PR40053, right? That needs some enhancement around MatchADDUS I think.
