Merge pull request #424 from ross144/main 
Fixed issue #412 The root cause was DTLB miss leads to page fault exception with concurrent I$ miss.  The HPTW hits all entries in the D$ and quickly faults.  However the I$ is still waiting on the main memory. The trap then interrupts the atomimicity of the bus fetch and breaks the next several instructions.

4a61d1b4f1 Fixed issue #412 
The root cause was DTLB miss leads to page fault exception with concurrent I$ miss.  The HPTW hits all entries in the D$ and quickly faults.  However the I$ is still waiting on the main memory.
The trap then interrupts the atomimicity of the bus fetch and breaks the next several instructions.

The simplest solution is to use CommittedF to delay Exceptions like with Interrupts.  Note this cannot happen with CommittedM.  If the ITLB misses and the D$ also need to fetch a from the bus an ITLB page fault exception will not trigger the trap until a few stages later.
