Matt Arsenault 555e7ee04c AMDGPU/GlobalISel: Don't use XEXEC class for SGPRs 
We don't use the xexec register classes for arbitrary values
anymore. Avoids a test variance beween GlobalISel and SelectionDAG>

Matt Arsenault f9a42ed0a7 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.
