Add tests for generalized lambda capture (C++14). NFC.
[analyzer] Add tests for generalized lambda capture (C++14). NFC.

Add tests demonstrating that the analyzer supports generalized lambda capture. This
support falls out naturally from the work Gábor Horváth did adding C++11 lambdas to
the analyzer.
