[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).

Interestingly, this many year old (when I last looked I remember 2010ish)
checker was committed without any tests, so I thought I'd implement them, but I
was shocked to see how I barely managed to get it working. The code is severely
outdated, I'm not even sure it has ever been used, so I'd propose to move it
back into alpha, and possibly even remove it.

[analyzer] Initial commit for the upcoming refactoring of the IteratorChecker.
The new checker currently contains the very core infrastructure for tracking
the state of iterator-type objects in the analyzer: relating iterators to
their containers, tracking symbolic begin and end iterator values for
containers, and solving simple equality-type constraints over iterators.
A single specific check over this infrastructure is capable of finding usage of
out-of-range iterators in some simple cases.

[analyzer] Turn suppress-c++-stdlib on by default
We have several reports of false positives coming from libc++. For example,
there are reports of false positives in std::regex, std::wcout, and also
a bunch of issues are reported in https://reviews.llvm.org/D30593. In many
cases, the analyzer trips over the complex libc++ code invariants. Let's turn
off the reports coming from these headers until we can re-evalate the support.
We can turn this back on once we individually suppress all known false
positives and perform deeper evaluation on large codebases that use libc++.
We'd also need to commit to doing these evaluations regularly as libc++
headers change.
