Subject: Move LiveProcess::create() from arch-specific files bcak to main
 LiveProcess, then automatically select ISA based on object file type.  Now
 simulation scripts no longer need to care about the ISA, as they can just
 call LiveProcess().

configs/test/test.py:
    Script no longer cares about ISA.

    Move create() from arch-specific files back to
    main LiveProcess, then automatically select ISA
    based on object file type.
