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.

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.

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