MLP DSP functions x86-optimized.
12.59% overall speedup in x86_32
 9.98% overall speedup in x86_64
compared to gcc 4.3.3

It breaks on x86_64 with PIC because the MANGLE macro appends (%%rip), which
is not wanted for labels.

Just aligning it on the stack would have been possible but less reliable
and without any real benefit.

Now the sign of audio samples in ffvorbis output is the same as in original
uncompressed audio file and this also allows the use of tiny_psnr to compare
ffvorbis with libvorbis/tremor.
