[Analyzer] Iterator Checker - Part 6: Mismatched iterator checker for constructors and comparisons

Extension of the mismatched iterator checker for constructors taking range of first..last (first and last must be iterators of the same container) and also for comparisons of iterators of different containers (one does not compare iterators of different containers, since the set of iterators is partially ordered, there are no relations between iterators of different containers, except that they are always non-equal).
