3027b4a5 - [AMDGPU] Fix iterator invalidation during frame lowering (#163952)

[AMDGPU] Fix iterator invalidation during frame lowering (#163952) I was a bit too eager to remove the SI_WHOLE_WAVE_FUNC_SETUP instruction during prolog emission. Erasing it invalidates MBBI, which in some cases is still needed outside of `emitCSRSpillStores`. Do the erasing at the end of prolog insertion instead.
