Summary: Moving SMRD to VMEM in SIFixSGPRCopies is rather bad for performance if the load is really uniform. So select the scalar load intrinsics directly to either VMEM or SMRD buffer loads based on divergence analysis. If an offset happens to end up in a VGPR -- either because a floating point calculation was involved, or due to other remaining deficiencies in SIFixSGPRCopies -- we use v_readfirstlane. There is some unrelated churn in tests since we now select MUBUF offsets in a unified way with non-scalar buffer loads.
