Compiles now (with CPU_MODELS=SimpleCPU), but hangs

on execution.

configs/test/test.py:
    Move test binary out of m5-test, don't depend on
    m5-test/Benchmarks.
python/m5/objects/System.py:
    Split out full-system-only parameters (lost in merge).
sim/system.cc:
    Need to be able to instantiate System directly in SE mode
    (lost in merge).
sim/system.hh:
    A few more functions here are FS-only.
configs/test/hello:
    Add in binary.
