In preperation for later optimization in the CPU pipeline
implementation, this commit refactors the arm/thumb exec functions to return a
CpuAction (Whether to advance the program counter or to flush the
pipeline)
Currently, a lot of host cycles are wasted in the arm7tdmi pipeline
Refill1 & Refill2 states. Optimizing these steps out would make the CPU
a bit faster.
