*All the computation time is spent in ff_sbr_apply() and it's
children. If it isn't called from ff_sbr_apply() making it 100% faster
isn't going to buy us anything.
*Right now the synthesis filterbank is written on top on an MDCT. With
appropriate SIMD functions it may make sense to move it to an FFT.
Right now the MDCT version is much faster.
*SIMD placeholder patch not included
