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.

oldish EXEC_RETURN handling with a throw/catch mechanism since we

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
