Summary:
This diff avoids that an integer value is pruned to the bottom by
comparing to a pointer.
For example, before this diff,
assume((int*)x == p);
assume((int*)x != p);
where x is an integer, x is pruned to the bottom in both of the assume
cases. So, there were some, unintentional and false, unreachable
code.
