  Log Message:
  -----------
  AMDGPU: Scratch instructions are trivially disjoint from SMEM and buffer instructions (#65287)

Scratch instructions are always in addrspace(5), which can only alias
with flat (and itself). SMEM and buffer instructions can never reference
those address spaces, so they are trivially disjoint.
