Comment:

 By doing exhaustive check over the entire ranges of signed and unsigned
 integers we prove that `intptr_t` and `void *` interoperability is
 possible for all values in these ranges, instead of the ones we deem to be
 dangerous. I'm putting this code into `test-slow` to address the problem
 of it taking too long.

 On what basis do we deem above ranges to be dangerous?
