  AMDGPU: Clear subreg when folding immediate copies

This was getting reinterpreted as operand target flags, and appearing
as as <unknown target flag>, resulting in unparseable MIR.

  AMDGPU: Fix handling of target flags when commuting instruction

If the original register operand had a subregister, it wasn't getting
cleared. This resulted in reinterpreted the subreg index as
unrecognized target flags, which produced unparseable MIR.
