Right, let's leave out the change for uint64, which works for visitors
that transparently convert -2^64..-1 to 2^63..2^64-1 or the other way
round.  String and QemuOpts visitors can still add the method, do proper
range checking and report the error themselves.

Also, Laszlo, your new visit_type_size should fall back to uint64 rather
than int.
