O3: Fixes fetch deadlock when the interrupt clears before CPU handles it. When this condition occurs the cpu should restart the fetch stage to fetch from the original execution path. Fault handling in the commit stage is cleaned up a little bit so the control flow is simplier. Finally, if an instruction is being used to carry a fault it isn't executed, so the fault propagates appropriately.
