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.

Vorbis optimizations from Brandon Low (part of patch 1387611). Reduces cpu boost ratio on a test track by about 6 percentage points. Also fixes broken simulator playback caused by my previous Tremor commit.
