The check is omitted in the name of (initial) simplicity of the
ocamlopt code generator, e.g. "for a start, let's map all arithmetic
operations to those of the hardware and see if that's good enough".
I'm not too concerned about the run-time penalty: integer division is
slow even on processors that have it in hardware.
