For GlobalISel, as a terrible hack, use SGPR_32 for things that should use SCC until booleans are solved. llvm-svn: 375267	2019-10-18 18:26:37 +00:00

AMDGPU: Relax 32-bit SGPR register class

Mostly use SReg_32 instead of SReg_32_XM0 for arbitrary values. This
will allow the register coalescer to do a better job eliminating
copies to m0.

For GlobalISel, as a terrible hack, use SGPR_32 for things that should
use SCC until booleans are solved.
