I added this functionality to Simulation.py and Options.py.  I use
--fast_forward on its own to create checkpoints, and then with
--standard_switch to warmup caches.  I've attached the diffs.

A word of caution:  I had to back out some of my other changes to
Simulation.py to create this diff, so I haven't tested this on its own.  But
it should be really close to what is needed.
