  Log Message:
  -----------
  AMDGPU: Make rewrite-vgpr-mfma-to-agpr-spill-multi-store.ll less allocator sensitive (#226913)

This test is sensitive to the exact split and spills which occur, and disappeared  under 
a future upstream improvement. Use basic RA with a fixed occupancy since it more
stably produces the spill pattern.

Also add a codegen reference test for the same kernel, so future codegen
improvements are visible.
