Kevin Lim bfd5eb2b08 Remove mem parameter. Now the translating port asks the CPU's dcache's peer for its MemObject instead of having to have a paramter for the MemObject.

    No need for mem parameter any more.
src/cpu/checker/cpu.cc:
    Use new constructor for simple thread (no more MemObject parameter).
src/cpu/checker/cpu.hh:
    Remove MemObject parameter.
src/cpu/memtest/memtest.hh:
    Ports now take in their MemObject owner.

    Remove mem parameter.
