Also add the option for the checker to update itself with the main CPU's state if it executes an instruction differently (so it will handle DMA timing errors properly).

arch/alpha/ev5.cc:
Fix up some stuff I missed in the last kernel stats checkin.
cpu/checker/cpu.cc:
Allow the checker to disable its kernel stats.
cpu/cpu_exec_context.cc:
Allow CPUExecContext to be created without kernelStats.
cpu/cpu_exec_context.hh:
Allow CPUExecContext to be created without kernelStats. Default usage leaves kernelStats on.

cpu/checker/cpu.cc:
Cleanup checker, give more useful warning messages.
Also fix bug
cpu/checker/cpu.hh:
Cleanup checker, use forward declaration instead of include.

arch/alpha/ev5.cc:
Move kernel stats out of CPU and into XC. Also be sure to check if the kernel stats exist prior to using them.

cpu/checker/cpu.cc:
Fixups for fetch fault being sent with the instruction.
cpu/o3/fetch_impl.hh:
cpu/ozone/front_end_impl.hh:
Send any faults generated at fetch along with a fake nop instruction to the back end. This avoids having to use direct communication to check if the entire front end has drained; it is naturally handled through the nop's fault being handled when it reaches the head of commit.
cpu/ozone/front_end.hh:
Add extra status TrapPending.
cpu/ozone/lw_back_end_impl.hh:
Fetch fault handled through a dummy nop carrying the fetch fault.
Avoid putting Nops on the exeList.
