  [AMDGPU] Mark s_getreg as having side effects instead of reading memory

s_getreg does not interact with anything else that is modelled as a
memory access either in IR or MachineIR.

  Log Message:
  -----------
  [AMDGPU] Mark s_get_waveid_in_workgroup as not reading memory

It is already marked as having side effects, at least in MIR. It does
not interact with anything else that is modelled as a memory access
either in IR or MachineIR.
