MemMMap/SimState: speed up SimState.get_mem() for large memories

make MemMMap use struct.Struct.unpack_from to read a whole page at
once, rather than doing a sequence of loads. This makes an ELF
binary statically-linked to glibc able to run many instructions per
second rather than one every tens of seconds or so.
