9ccb363ec3 bochs style decode/execute of FPU instructions.
With this coding style each instruction could be implemented separatelly even not together with current Bochs FPU emulator.
Step-by-step I am going to transfer all FPU instructions from current Bochs FPU emulator to new style and remove an old bugged emulator.
Anyway, now I could implement all currently missed FPU instructions without hacking wm-fpu-emu.

7f570b0150 Added PNI new streaming extensions instructions
PNI could be enabled by setting BX_SUPPORT_PNI in config.h
After the feature will be fully validation I'll also add configure option.

The implemntation is ~complete. I've missed only three FPU new opcodes of FUSTTP instruction and MONITOR/WAIT instructions.

Enjoy ! ;)
