ff88f3b13a Compare legion and m5 tlbs for differences
Only print faults instructions that aren't traps or faulting loads

src/cpu/exetrace.cc:
    Compare the legion and m5 tlbs and printout any differences
    Only show differences if the instruction isn't a trap and isn't a memory
    operation that changes the trap level (a fault)

    update the m5<->legion interface to add tlb data

551ba56ae2 little fixes i noticed while searching for reason for address range issues (but these weren't the cause of the problem).
RangeSize as a function takes a start address, and a SIZE, and will make the range (start, start+size-1) for you.

c7ad7b44eb Allow for multiple redirects to happen on a single cycle (only the one for the oldest instruction is passed on to commit).
This fixes a minor bug when multiple FU completions come back out of order (due to the order in which the FUs are freed up), and the oldest redirect isn't recorded properly.  The eon benchmark should run now.
