  AMDGPU: Handle folding frame indexes into add with immediate

Frame index materialization can fold the constant offset into
adds with immediates. The mubuf expansion is more complicated because
we have to also insert the shift, so restrict this to one use for now.
This is preparation to avoid regressions in a future patch.

This also misses some cases due to visitation order. It depends on
the immediate already folding into the instruction.
