4fff6d4603 Fixes to cache eliminating the assumption that the Packet is still valid after sending out a request.

288b98eb69 Fix it so that the cache does not assume to gave the packet it sent out via sendTiming.
Still need to fix upgrades to use this path

src/mem/cache/base_cache.cc:
    Copy the pkt to the MSHR before issuing the sendTiming where it may be changed/consumed
src/mem/cache/cache_impl.hh:
    Use copy of packet, because sendTiming may have changed the pkt
    Also, delete the copy when the time comes

a50e83c134 Fix assertion. I haven't tested it fully (I can't reproduce Lisa's error) but I believe it should fix what she's running into (which was definitely a bug).
src/cpu/o3/fetch_impl.hh:
    Move assertion to area where it should really always be true.  Sometimes you might recvRetry and not necessarily be blocked (if there was a squash).
