More cache fixes. Atomic coherence now works as well.

src/cpu/memtest/memtest.cc:
src/cpu/memtest/memtest.hh:
    Make Memtester able to test atomic as well
src/mem/bus.cc:
src/mem/bus.hh:
    Handle atomic snoops properly for cache->cache transfers
src/mem/cache/cache_impl.hh:
    Debug output.
    Clean up memleak in atomic mode.
    Set hitLatency.
    Still need to send back reasonable number for atomic return value.
src/mem/packet.cc:
    Add command strings for new commands
src/python/m5/objects/MemTest.py:
    Add param to test atomic memory.
