More progress... run a few instructions now, but die on the second

memory access (I think because we're deallocating our one and only
CpuRequest object).

base/loader/aout_object.cc:
base/loader/ecoff_object.cc:
base/loader/elf_object.cc:
    Add flag to force allocation of new pages on data writes.
cpu/simple/cpu.cc:
    Several minor fixes.
    Switch to atomic mode for now.
mem/physical.hh:
    Don't copy the packet to the response event, just keep a reference
    to the original.
mem/translating_port.cc:
mem/translating_port.hh:
    Add parameter to writeBlobFunctional() to force allocation of
    unallocated pages on writes.
