[PATCH] D105920: [AMDGPU] Init scratch only if necessary

[Tony Tye via Phabricator via llvm-commits]

t-tye added a comment.

It is also not necessary to request the scratch SRD to be set up in the User SGPRs. There is a significant performance cost for small kernels to requesting this unneeded set of 4 SGPRs to be initialized by the hardware.
