Clean up CPU stuff and make it use params structs

cpu/base_cpu.cc:
cpu/base_cpu.hh:
    Convert the CPU stuff to use a params struct
cpu/memtest/memtest.cc:
    The memory tester is really not a cpu, so don't derive from
    BaseCPU since it just makes things a pain in the butt.  Keep
    track of max loads in the memtest class now that the base class
    doesn't do it for us.
    Don't have any default parameters.

    Convert to use a params struct.
    remove default parameters

cpu/trace/opt_cpu.cc:
cpu/trace/opt_cpu.hh:
cpu/trace/trace_cpu.cc:
cpu/trace/trace_cpu.hh:
    this isn't really a cpu.  don't derive from BaseCPU
objects/MemTest.mpy:
    we only need one max_loads parameter
sim/main.cc:
    Don't check for the number of CPUs since we may be doing something
    else going on.  If we don't have anything to simulate, the
    simulator will exit anyway.
