AMDGPU/GlobalISel: Implement LDS G_GLOBAL_VALUE Handle the simple case that lowers to a constant. llvm-svn: 371424

AMDGPU/GlobalISel: Look through copies in getPtrBaseWithConstantOffset We may have an SGPR->VGPR copy if a totally uniform pointer calculation is used for a VGPR pointer operand. Also hack around a bug in MUBUF matching which would incorrectly use MUBUF for global when flat was requested. This should really be a predicate on the parent pattern, but the DAG always checked this manually inside the complex pattern.
