FS #7833 : Optimizations to the Vorbis codec:
...
- ARM assembly version of parts of mdct,
- special case for vorbis_book_decodevv_add for 2 channels and even book->dim,
- store the output in vb->pcm if possible, as it is usually in IRAM as
opposed to v->pcm.

Recude iram usage for the Vorbis decoder a little. Makes it possible to build with gcc 4.0.3.
