TODO: This allocates 32-bit ints on other CPU architectures. Since
we're small/tiny model only, for now we can get away with allocating
always 16-bit int parameters, but in the future, when we implement
other memory models, this mechanism has to be extended somehow to
support 32-bit addresses on a 16-bit CPU.
