Adding testcases in unittest/AST/SourceLocationTest.cpp as suggested by @aaronballman

Interestingly, without my change tests for function declarations pass. Only member functions fail:

Not sure why would they take different codepaths, throw and noexcept are C++(11) specific. Is the code parsed as C++11 anyway for Verifiers?
