My further mdct optimizations (which patch I have not posted since it
shouldn't be controversial) depends on split-radix. Merging mdct reorder
with mdct post-rotation is better than merging it with windowing. Yes,
post-rotation and windowing could also be merged (if you have enough
registers; maybe not on x86_32), but that would be even more complex than
my previous windowing patch.
