  Log Message:
  -----------
  [AMDGPU] S_SET_GPR_IDX_ON can be passed an immediate index (#125086)

Oversight found by ISel fuzz effort. Assuming the argument is a
register, in some cases it can be an immediate. Tablegen's type for the
instruction is SSrc_b32, i.e. register or immediate fine. Added the
repro from the bug reporter as a test case - prior to this patch llvm
will assert in getReg.

Fixes SWDEV-508589
