c13eba29ff 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.

41cea75095 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.

7e33f16aee Tweaked IRAM usage in the Vorbis codec. Speeds up decoding by about 10% on a couple of test files.

0a3f8e0924 Vorbis opts: keep floor1 lookup table in IRAM. 
Slightly faster 16-bit clipping function.
Misc: changed tabs for spaces to conform with Rockbox coding standards.

024db0a766 Basic optimizations of the Vorbis decoder for the ihp-1x0. 
Capable of real-time decoding with cpu freq at 120mhz.
