f51189fa4d 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.

shifts leading to a deteriorated sound quality for some samples.

f5a0d61a1b Further optimization and minor clean up of atrac codec: Unroll iqmf_dewindowing for non-ARM speeds up decoder by +10% on H300. Removed some non-used arrays. Codec is still not fully realtime on Coldfire targets.

8722c6f2bb Make deceodeSpectrum() store the spectral coefficients of odd bands in reverse order, rather than having to reverse them in IMLT(). Also saves 0.11MHz, ~0.16% speedup on PP5024.

2dbb424eb9 Further performance optimization of the atrac3 decoder. Rework the internal sample representation and usage of dsp routines. For now a quick and dirty solution is used to add a fract part of 2 bits. Through this several buffers and functions as well as copy loops could be removed. Furthermore add some ASM for coldfire and place some additional data in IRAM on PP5022/24 and X5/M5. Speedup on ARM: +3%, speedup on Coldfire: +639%. Both ARM and Coldfire can decode in realtime now.
