f62e031f56 CPU: Change Interrupt/Halt behavior 
- Run NOP instead of instruction if an Interrupt is asserted before
fetching the opcode.
- Start Interrupt at the end of a single M-Cycle instruction and not
Halted.
- DMG: Exit Halt if Interrupt is asserted at the beginning of the
M-Cycle (GBC: At the end of the M-Cycle).

Starting the Interrupt takes 4 M-Cycles. It can take an extra M-Cycle
depending on the above conditions.
