[Analyzer] Handle pointer implemented as iterators in iterator checkers
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).

[Analyzer] Iterator Checkers: Replace `UnknownVal` in comparison result by a conjured value
Sometimes the return value of a comparison operator call is
`UnkownVal`. Since no assumptions can be made on `UnknownVal`,
this leeds to keeping impossible execution paths in the
exploded graph resulting in poor performance and false
positives. To overcome this we replace unknown results of
iterator comparisons by conjured symbols.

[Analyzer][NFC] Separate white-box tests for iterator modelling from iterator checker tests
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.

[Analyzer] Iterator Checkers - Make range errors and invalidated access fatal
Range errors (dereferencing or incrementing the past-the-end iterator or
decrementing the iterator of the first element
[Analyzer] Iterator Checkers - Make range errors and invalidated access fatal
Range errors (dereferencing or incrementing the past-the-end iterator or
decrementing the iterator of the first element of the range) and access of
invalidated iterators lead to undefined behavior. There is no point to
continue the analysis after such an error on the same execution path, but
terminate it by a sink node (fatal error). This also improves the
performance and helps avoiding double reports (e.g. in case of nested
iterators).

This patch adds support for the following operations in the iterator checkers: assign, clear, insert, insert_after, emplace, emplace_after, erase and erase_after. This affects mismatched iterator checks ("this" and parameter must match) and invalidation checks (according to the standard).

This patch adds support for the following operations in the iterator checkers: push_back, push_front, emplace_back, emplace_front, pop_back and pop_front. This affects iterator range checks (range is extended after push and emplace and reduced after pop operations) and invalidation checks (according to the standard).
