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.
