All these use is TARGET_INT_BIT, and all they use it for is to do
something halfway sensible when you say "print foo" and there's no
debug info for foo, or "print foo()".

I was going to suggest that we use uint32_t instead and avoid having
to make these architecture independent, but I just remembered that
there was a proposal long ago to use "long" (or maybe "uintptr_t")
instead.  So we'd just need to make them architecture specific again
anyway.  This looks fine to me.
