Giacomo Travaglini 23366a2899 cpu: Dispatch PCEvents to the CheckerCPU SimpleThread 
Moving PCEvents scheduling from the system to the Thread [1]
requires us to forward PCEvents to the CheckerCPU thread.

We will otherwise encounter a divergence with the checker when trying to
emulate a SkipFunction in the host (e.g. udelay on Arm).
While the original thread will correctly emulate it and jump to the next
instruction in the binary), the Checker's thread, with no scheduled
PCEvent, will jump straight into the function.

This is fixing realview64-o3-checker.py regression
