[PATCH] D101633: [AMDGPU] Set number vgprs used in PS shaders based on input registers actually used

[Carl Ritson via Phabricator via llvm-commits]

critson added a comment.

To confirm, this reduces the minimum number of VGPRs used by PS?
I am not sure the language in the description makes this clear.

The code makes sense to me.
Since this has been in review for a while now, assuming it passes CTS, we should probably accept it?
