        separatly.
        (bc1): Handle mips IV which do not have a delaed FCC separatly.
        (SDR): Mask paddr when BigEndianMem, not the converse as specified
        in IV3.2 spec.

functions sim_read & sim_write.  This eliminates all code (other than
in load_memory & store_memory) that makes assumptions about the
implementation of the underlying memory model.
