Summary: Add check misc-dangling-handle to detect dangling references in value handlers like std::experimental::string_view. It provides a configuration option to specify other handle types that should also be checked. Right now it detects: - Construction from temporaries. - Assignment from temporaries. - Return statements from temporaries or locals. - Insertion into containers from temporaries.
