4547da80ea Fixed bug #49. 
FFLAGS was updated while the pipeline was stalled.
Also I found serveral performance counters which had similar issues.

659b511616 Lee Moore found another bug using imperas. 
An ITLB miss concurrent with a d cache flush did not interlock.
The LSU should suppress the d cache flush until the hptw fills the missing tlb entry.
