Minor functionality updates.

Browse source 
SConstruct:
    Include an option to specify the CPUs being tested.
src/cpu/SConscript:
    Checker isn't SMT right now, so don't do SMT tests with the O3CPU if we're using the checker.
src/python/m5/objects/O3CPU.py:
    Include default options.  Unfortunately FullO3Config.py is still needed because it specifies which FUPool is being used.
tests/SConscript:
    Several minor updates (sorry for one commit).  Updated the copyright and fixed some m5 style issues.  Also added the ability to specify which CPUs to run the tests on.
