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

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.

Mem: don't log loads when dumping, you'll see the memory dump anyway

without logging every single load needed to create the memory dump.
