Subject: More major reorg of cache.  Seems to work for atomic mode now, timing
 mode still broken.

configs/example/memtest.py:
    Revamp options.
src/cpu/memtest/memtest.cc:
    No need for memory initialization.
    No need to make atomic response... memory system should do that now.
src/cpu/memtest/memtest.hh:
    MemTest really doesn't want to snoop.
src/mem/bridge.cc:
    checkFunctional() cleanup.
