29f45d6203 Imperas found a bug with the Fence.I instruction.
If a fence.i directly followed a store miss, the d$ would release Stall during the cache line write.
Then transition to ReadHold.  This cause the d$ flush to go high while in ReadHold.  The solution is
to ensure the cache continues to assert Stall while in WriteLine state.

There was a second issue also.  The D$ flush asserted FlushD which flushed the I$ invalidate.
Finally the third issue was CacheEn from the FSM needs to be asserted on an InvalidateCache.
