74e8abd37e Switch out fixups for the CPUs.
cpu/cpu_exec_context.cc:
    Be sure to switch over the kernel stats so things don't get messed up.  This may lead to weird stats files for sampling runs (detailed stats should be correct, regardless of which kernel stats this is defined on).
cpu/o3/cpu.cc:
    Updates for switching out.  Also include a bunch of debug info if needed.
cpu/o3/fetch_impl.hh:
    Switch out properly.
cpu/o3/inst_queue.hh:
cpu/o3/inst_queue_impl.hh:
    Comment out unused stats (they made the stats file huge).
cpu/o3/lsq_unit.hh:
cpu/o3/lsq_unit_impl.hh:
    Add in new stat.
cpu/o3/rename.hh:
    Fix up for switching out.
cpu/o3/rename_impl.hh:
    Fix up for switching out.  Be sure to mark any Misc regs as ready if their renamed inst got squashed from being switched out.
cpu/ozone/cpu_impl.hh:
cpu/simple/cpu.cc:
    Switch out fixup.
sim/eventq.hh:
    Make CPU switching more immediate.
    Also comment out the assertion, as it doesn't apply if we're putting it on an inst-based queue.

a514bf2150 Comments and code cleanup.
cpu/activity.cc:
cpu/activity.hh:
cpu/o3/alpha_cpu.hh:
    Updates to include comments.
cpu/base_dyn_inst.cc:
    Remove call to thread->misspeculating(), as it's never actually misspeculating.

8a9416ef8d Small fixes to O3 model.
cpu/o3/alpha_dyn_inst.hh:
    Set the instResult using a function on the base dyn inst.
cpu/o3/bpred_unit_impl.hh:
    Don't need to reset the state.
cpu/o3/commit_impl.hh:
    Mark instructions as completed.

    Wait until all stores are written back to handle a fault.
cpu/o3/cpu.cc:
    Clear instruction lists when switching out.
cpu/o3/lsq_unit.hh:
    Allow wbEvent to be set externally.
cpu/o3/lsq_unit_impl.hh:
    Mark instructions as completed properly.  Also use events for writing back stores even if there is a hit in the dcache.

a8b03e4d01 Updates for O3 model.
arch/alpha/isa/decoder.isa:
    Make IPR accessing instructions serializing so they are not issued incorrectly in the O3 model.
arch/alpha/isa/pal.isa:
    Allow IPR instructions to have flags.
base/traceflags.py:
    Include new trace flags from the two new CPU models.
cpu/SConscript:
    Create the templates for the split mem accessor methods.  Also include the new files from the new models (the Ozone model will be checked in next).
cpu/base_dyn_inst.cc:
cpu/base_dyn_inst.hh:
    Update to the BaseDynInst for the new models.
