Matt Arsenault 86815a1842 AMDGPU/GlobalISel: Permit mapping G_FRAME_INDEX to sgprs (#101325) ...

eliminateFrameIndex should now properly handle materializing
frame indices in SGPRs, so treat this like the other constant
operand types.

On average this will produce worse code; we need to detect
VGPR uses, and improve SGPR->VGPR frame index folds.
