Sean Cross d1e215e312 caches: work without writeBack stage
In the case of an MMU miss, the data caches will create a retry branch port.
These currently implicitly go into the memory/writeBack stage, however
not all CPUs have this stage.

Place the retry branch port into the correct stage.

Sean Cross b2f387ccac MmuPlugin: fix generation without writeBack stage
If there is no writeBack stage, the elaboration step would hit a
NullPointerException when trying to insert into the writeBack stage.

Instead, pull from the most recent stage, which is where MMU access
should reside.
