Filled in some missing holes: -Implement PMC inc/dec functions and add ops to engine. 'inc P0, 5' is faster than 'set P0, P1, 5' which uses a vtable. -Corrected 'inc Nx, Ny' to 'inc Nx, Iy' as per the PDD -Added missing 'add Nx, Ny, Iz' op
Updated mops_p.pasm to use dec op, however, the intent was not to optimize mops_p benchmark, but to optimize for a very common operation, which mops_p just happens to do. We now need to re-evaluate mops_p and how to accurately represent a cross-section of operations and not a specific case. Er, hmm we might need a few new tests, I was too lazy to write them, I did fix the existing ones for the erroneous inc Nx, Ny op. Btw, mops_p runs 20% faster, for now, but I wouldn't get too excited since it only uses 2 specific ops. -Melvin
