fft: port FFT/IMDCT 3dnow functions to yasm, and disable on x86-64.
64-bit CPUs always have SSE available, thus there is no need to compile
in the 3dnow functions. This results in smaller binaries.

Move dct and rdft definitions to separate files
This leaves fft.h with only the core FFT and MDCT definitions
thus making it more managable.
