[AMDGPU] Change getLdStRegisterOperand to !cond for better diagnostic (#95475)
If you would hit the unexpected case in these !if trees, you'd get an
error message like "error: Not a known RegisterClass! def VReg_1..."
This can happen when changing code quite indirectly related to these
class definitions. We can use !cond here, which has a builtin facility
to throw an error if no case in the !cond statement is hit.
