Another pass of minor changes in preparation for new protocol.
src/mem/cache/cache_impl.hh:
src/mem/cache/coherence/simple_coherence.hh:
Get rid of old invalidate propagation logic in preparation
for new multilevel snoop protocol.
src/mem/cache/coherence/coherence_protocol.cc:
L2 cache now has protocol, so protocol must handle ReadExReq
coming in from the CPU side.
src/mem/cache/miss/mshr_queue.cc:
Assertion is failing, so let's take it out for now.
src/mem/packet.cc:
src/mem/packet.hh:
Add WritebackAck command.
Reorganize enum to put responses next to corresponding requests.
Get rid of unused WriteReqNoAck.
