Fixes#132010
Associative containers in STL has an unique `insert` overload member
function comparing to un-associative
containers(https://en.cppreference.com/w/cpp/container/unordered_set/insert):
```
template< class InputIt >
void insert( InputIt first, InputIt last );
```
Add support for this `insert` overload in `MismatchedIteratorChecker`,
verify if `first` and `last` belongs to the same container in this case.
Iterators are an abstraction of pointers and in some data structures
iterators may be implemented by pointers. This patch adds support for
iterators implemented as pointers in all the iterator checkers
(including iterator modeling).

The recently committed debug.IteratorDebugging checker enables
standalone white-box testing of the modelling of containers and
iterators. For the three checkers based on iterator modelling only
simple tests are needed.

Checking whether two regions are the same is a partially decidable problem:
either we know for sure that they are the same or we cannot decide. A typical
case for this are the symbolic regions based on conjured symbols. Two
different conjured symbols are either the same or they are different. Since
we cannot decide this and want to reduce false positives as much as possible
we exclude these regions whenever checking whether two containers are the
same at iterator mismatch check.

This checker warns you when you re-use an object after moving it.

In earlier Clang Static Analyzer versions `check::Bind() was not invoked for
parameter passing, so we needed a trick which is not needed anymore. However
add the tests to ensure its working.
