Fix various things in the instruction emulation code:

Browse Source 
- Add ability to control whether or not the emulator advances the
    PC register (in the emulation state), if the instruction itself
    does not change the pc value..

    - Fix a few typos in asm description strings.

    - Fix bug in the carry flag calculation.
