30d286d859 libwmapro: slightly shorter and faster inline asm fixed point multiplication routines, speedup is ~0.5%. Also don't lie to gcc about which vars are changed by the asm.

87d59ab56c Submit part of FS#11498. Major speedup for WMA Professional on ARM and Coldfire CPUs. Introduce asm routines for multiplications, move arrays with major impact on decoding speed to IRAM. Speeds up decoding by 25% on PP5022 and 34% on mcf5249.

025eed5c74 libwmapro: coldfire asm for vector_fixmul_window, gives a speedup of ~13%, drop the add_bias argument for the vector_fixmul_window function, since it was always 0

ec4ee48318 Complete the conversion of WMA Pro to fixed point. Floating point code is still there for better history and to have a returning point in svn should something go wrong.

d884af2b99 Partial conversion of the wmapro decoder to fixed point arithmetic. Currently inverse quantization & rescaling,
imdct and windowing are all in fixed point.
