[PATCH] D76135: [MachineLICM] Don't treat cross copies as cheap

[Dave Green via Phabricator via llvm-commits]

dmgreen added a comment.

I have altered the way that MVE VDUP are lowered, and we end up with a VMOV now instead of using a COPY. That means I don't need this any more for MVE at least.

@arsenm, let me know whether you want me to continue with this for AMDGPU or not.
