Two updates that got combined into one ChangeSet accidentally. They're both pretty simple so they shouldn't cause any trouble.

First: Rename FullCPU and its variants in the o3 directory to O3CPU to differentiate from the old model, and also to specify it's an out of order model.

Second: Include build options for selecting the Checker to be used.  These options make sure if the Checker is being used there is a CPU that supports it also being compiled.

SConstruct:
    Add in option USE_CHECKER to allow for not compiling in checker code.  The checker is enabled through this option instead of through the CPU_MODELS list.  However it's still necessary to treat the Checker like a CPU model, so it is appended onto the CPU_MODELS list if enabled.
configs/test/test.py:
    Name change for DetailedCPU to DetailedO3CPU.  Also include option for max tick.
src/base/traceflags.py:
    Add in O3CPU trace flag.
src/cpu/SConscript:
    Rename AlphaFullCPU to AlphaO3CPU.

    Only include checker sources if they're necessary.  Also add a list of CPUs that support the Checker, and only allow the Checker to be compiled in if one of those CPUs are also being included.
src/cpu/base_dyn_inst.cc:
src/cpu/base_dyn_inst.hh:
    Rename typedef to ImplCPU instead of FullCPU, to differentiate from the old FullCPU.

src/cpu/o3/alpha_cpu.cc:
src/cpu/o3/alpha_cpu.hh:

    Also #ifdef the checker code so it doesn't need to be included if it's not selected.
