Add an alternative avx2 s32_to_f32d implementation that doesn't use the gather function for when gather is slow. Don't overwrite the orinal cpu_flags but store the selected flags in a new variable. Use this to debug the selected function cpu flags. Build libraries with defines from previous libraries so that we can reuse functions from them. We can then remove the SSE2 | SLOW_GATHER function selection from the list. We will now select avx2 and it will then switch implementations based on the CPU flags.
