Artem Dergachev 61199443fe [analyzer] Enable cfg-temporary-dtors by default.
Don't enable c++-temp-dtor-inlining by default yet, due to this reference
counting pointe problem.

Otherwise the new mode seems stable and allows us to incrementally fix C++
problems in much less hacky ways.

constructing into simple variables.

Matthias Gehre 351c218d15 CFG: Add CFGElement for automatic variables that leave the scope
Summary:
This mimics the implementation for the implicit destructors. The
generation of this scope leaving elements is hidden behind
a flag to the CFGBuilder, thus it should not affect existing code.

Currently, I'm missing a test (it's implicitly tested by the clang-tidy
lifetime checker that I'm proposing).
I though about a test using debug.DumpCFG, but then I would
have to add an option to StaticAnalyzer/Core/AnalyzerOptions
to enable the scope leaving CFGElement,
which would only be useful to that particular test.

Any other ideas how I could make a test for this feature?
