Implement partial block cache invalidation. Rewrite core cached blocks
...
execution loop with a Duff's device. Gather some predecode time statistics.
This shows that only around 2% of total emulation time is spent for
predecoding the instructions.

Optimized pointers to non virtual member functions. This reduces space

and overhead since runtime checks are eliminated. Actually, it yields

Integrate spcflags handling code to kpx_cpu core. We can also remove
...
oldish EXEC_RETURN handling with a throw/catch mechanism since we
do have a dependency on extra conditions (invalidated cache) that
prevents fast execution loops.

Rewrite interrupts handling code so that the emulator can work with a
...
predecode cache. This implies to run in interpreted mode only while
processing EmulOps or other native (nested) runs.
Note that the FLIGHT_RECORDER with a predecode cache gets slower than
without caching at all.
