PSP: Slightly more aggressive optimisation

Browse Source 
- O3 flag replacing O2 for higher level of optimisation. Potentially unstable, but works for Wii U RetroArch along with other PSP emulators. I don't see why not.
- fsingle-precision-constant to simplify some operations. Should be safe while being more performant due to using less memory traffic and may lessen load on the CPU because of the simplification.
