[PATCH] D82451: [AMDGPU] Fix DPP Combiner:

[Jay Foad via Phabricator via llvm-commits]

foad added a comment.

> 1. skip multiple per instruction DPP register usage.
> 2. don't combine when DPP register is used as part of superreg/supersubreg.
> 
>   I had to refactor the code to fix the first issue,

Would it make sense to split this patch into two or three? Refactoring, fix bug 1, fix bug 2?
