Part of the fft8() function corresponds to the BUTTERFLIES macro,
so use it.

7f6e05cdfd ac3enc: simplify sym_quant() 
These expressions are equivalent since levels is always odd, and
overflow is impossible due to the constraints set by the assert().

4c886d613d Detect byte-swapped AC-3 and support decoding it directly. 
This allows the AC-3 decoder to be used directly with RealMedia
decoders that unlike the libavformat one do not byte-swap automatically.
Since the new code is only used in case we would fail directly otherwise
there should be no risk for regressions.

certainly not mean it is ok to crash.
