O3: When waiting to handle an interrupt, let everything drain out.
Before this change, the commit stage would wait until the ROB and store queue were empty before recognizing an interrupt. The fetch stage would stop generating instructions at an appropriate point, so commit would then wait until a valid time to interrupt the instruction stream. Instructions might be in flight after fetch but not the in the ROB or store queue (in rename, for instance), so this change makes commit wait until all in flight instructions are finished.
