Stanislav Gatev af98b0af67 [clang][dataflow] Add analysis that detects unsafe accesses to optionals 
This commit reverts e0cc28dfdc and moves
UncheckedOptionalAccessModelTest.cpp into clang/unittests/Analysis/FlowSensitive,
to avoid build failures. The test will be moved back into a Models subdir
in a follow up patch that will address the build configuration issues.

Original description:

Adds a dataflow analysis that detects unsafe accesses to values of type
`std::optional`, `absl::optional`, or `base::Optional`.

// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:
