b5736ba4ef alpha:o3:simple: update simout/err files
A few prior changesets have changed the gem5 output in a way that wont cause
errors but may be confusing for someone trying to debug the regressions. Ones that I caught
were:
- no more "warn: <hash address"
- typo in the ALPHA Prefetch unimplemented warning

Additionaly, the last updated stats changes rearrange the ordering of the stats output even though
they are still correct stats (gem5 is smart enough to detect this). All the regressions pass
w/the same stats even though it looks like they are being changed.

this will safeguard future code from trying to remove

5ef0b7a9db inorder/dtb: make sure DTB translate correct address
The DTB expects the correct PC in the ThreadContext
but how if the memory accesses are speculative? Shouldn't
we send along the requestor's PC to the translate functions?

561c33f082 inorder: dont handle multiple faults on same cycle
if a faulting instruction reaches an execution unit,
then ignore it and pass it through the pipeline.

Once we recognize the fault in the graduation unit,
dont allow a second fault to creep in on the same cycle.

0bfdf342da inorder: explicit fault check

by making the fault check it's own separate command
that can be put on an instruction schedule.

f268d7d004 alpha: make hwrei a control inst
this always changes the PC and is basically an impromptu branch instruction. why
not speculate on this instead of always be forced to mispredict/squash after the
hwrei gets resolved?

The InOrder model needs this marked as "isControl" so it knows to update the PC
after the ALU executes it. If this isnt marked as control, then it's going to
force the model to check the PC of every instruction at commit (what O3 does?),
and that would be a wasteful check for a very high percentage of instructions.
