tests/configs/o3-timing-mp.py:
tests/configs/o3-timing.py:
    Clean up configs by removing FullO3Config and instead using default values.
src/python/m5/objects/FUPool.py:
    Add in default FUPool.
src/python/m5/objects/O3CPU.py:
    Use defaults better.  Also set checker parameters, and fix up a config bug.
