The FMA4 functions from libavresample's audio_mix need to be handled
differently. Disabling them if avxslow is true is pointless since no
CPU out there currently has FMA4 and a fast float execution unit. So
I'm thinking about duplicating them and doing:
FMA3 YMM/XMM for current Intel CPUs (Basically, renaming the existing
functions)
FMA4 XMM for current AMD stuff (Regardless of x86_32 or x86_64).
I'll see about implementing that in the coming days.
