  AMDGPU: Add baseline tests for some bitcast lowering

These introduce stack lowering. Somehow it manages to get cleaned
up in the gfx9 cases (leaving a dead object behind), but gfx12
still has leftover memory instructions.

  DAG: Avoid introducing stack usage in vector->int bitcast int op promotion

Avoids stack usage in the v5i32 to i160 case for AMDGPU, which appears
in fat pointer lowering.
