Subject: [PATCH] [AMDGPU] Add baseline test to show spilling of wmma scale.
 NFC

This is to show the spilling of WMMA scale values which are limited
to low 256 VGPRs. We have free registers, just RA allocates low 256
first.

+; FIXME: Scale operands of WMMA are limited to low 256 VGPRs
+;        currently we are spilling it because all low VGPRs are occupied even though our budget is higher.
+; Make sure we do not spill scale operands because of the low 256 restriction.
