Checks whether two values of type int_type are equal.
Formally,
- if there exist values a and b such that c1 == X::to_int_type(a) and c2 == X::to_int_type(b), yields the same as X::eq(a,b)
- otherwise, if c1 and c2 are both copies of X::eof(), yields true
- otherwise, if one of c1 and c2 is a copy of X::eof() and the other is not, yields false
- otherwise, the result is unspecified
