I don't think there's an inherent reason we need to use INT_CST for
internal counters.  We do however need to make sure that we're matching
host vs. target overflow, etc., correctly; we can't use 32-bit counters
for a 64-bit target, or vice versa.  Unless we have a host integer type
that is documented as being as wide as target size_t for all possible
targets, we have to be careful; in general, we might have to invent some
other bignum type to use.
