PowerPC bugfixes:
- must clear carry bit when doing addic with a zero immediate value
- fix missing RETURN in micro-operation that would lead to random failures
and crashes
- add USE_PRECISE_EMULATION compilation-time option to choose between
getting exact floating point results and fast but less accurate computation.
