The "execute" portion of IEW is really just the last cycle of execution, at which point execute() gets called. Execution begins inside the IQ, when it schedules FUs for specific instructions. As a result, the Execute stage should just pull all completing instructions out of the IQ stage and execute them.
Limiting the number of writebacks outstanding must still be done.

TimingSimpleCPU, which use atomic and timing memory accesses
respectively. Common code is factored into the BaseSimpleCPU class.
AtomicSimpleCPU includes an option (simulate_stalls) to add delays
based on the estimated latency reported by the atomic accesses.
Plain old "SimpleCPU" is gone; I have not updated all the config
