cpus: don't credit executed instructions before they have run

Browse source 
Outside of the vCPU thread icount time will only be tracked against
timers_state.qemu_icount. We no longer credit cycles until they have
completed the run. Inside the vCPU thread we adjust for passage of
time by looking at how many have run so far. This is only valid inside
the vCPU thread while it is running.
