HA success, that's a full complex number RADIX2 in-place FFT, it uses
"Vertical-First" mode, and regs 24 thru 27 for temporary scalars in
the middle of each loop.
now comes the analysis part, for ways to optimise this.
i have a feeling it's time to extend SVSTATE to 64 bit and to start
storing "Vertical-First" mode bit, and some hints and other
persistence state, in it.
