I got 64-bit FFI working about five years ago but we never got it merged
into the VM (sorry). See http://bugs.squeak.org/view.php?id=7237

Those patches would be pretty badly bit-rotted by now, so I'm not
sure of the current state of affairs. I would anticipate a few issues,
because getting it to work in the old FFI was not trivial. It's
definitely worth getting this working again, but it may take a bit
of work to make it happen. Maybe it's easier with Eliot's more recent
work, because I think the assembler glue goes away and that may
simplify matters.
