Oh, I forgot to mention _why_ on the majority of transforms it's slower than
FFTW.
It's simple - we don't hard
This commit adds a pure x86 assembly SIMD version of the FFT in libavutil/tx.
The design of this pure assembly FFT is pretty unconventional.
On the lowest level, instead of splitting the complex numbers into
real and imaginary parts, we keep complex numbers together but split
them in terms of par
