[PATCH] D70379: [AMDGPU] Reserving VGPR for future SGPR Spill

[Saiyedul Islam via Phabricator via llvm-commits]

saiislam updated this revision to Diff 262485.
saiislam added a comment.

Fixed failing test cases. Now VGPR reservation happens in an
independent function and doesn't overload allocateSGPRSpillToVGPR.
Updated test case to hard code usage of all but one VGPRs and use
it for SGPR spill.
