FS#12117: Use more IRAM for atrac3. Speeds up decoding from 1-2% (PP5022, PP5024, S5L870x) to 11% (MCF5250).

Commit FS#11709 by me. Introduces ARMv5E optimized iQMF for atrac3 based on packed multiply instructions. Additionally, improves scheduling on arm9 and arm11 and forces cache alignment of buffers on all targets. Accuracy is slightly reduced, but still greater then 16 bit. Clip+ CPU clock required for LP2 files decreases by 13MHz and ARM11 by 18MHz. No performance or accuracy changes on armv4 or non-arm.

libatrac: Coldfire asm for atrac3_iqmf_dewindowing, speeds up decoding of my atrac3 rm file by 45%. Based on preliminary patch by Andree Buschmann

libatrac: Set the emac mode on coldfire, fixes whitenoise output if playing an atrac file after using a codec that sets macsr to integer mode.
