[PATCH] D12060: AMDGPU: Fix not adding exec to defs of cmpx instruction pseudos

[Matt Arsenault via llvm-commits]

arsenm created this revision.
arsenm added a reviewer: tstellarAMD.
arsenm added a subscriber: llvm-commits.

This was only set on the final _si/_vi version, but not on the pseudos most of codegen sees.

No test since these instructions aren't used yet.
