Implement type trait primitives used in the latest edition of the Microsoft standard C++ library type_traits header. With this change we can parse much of the Visual Studio 2013 standard headers, particularly anything that includes <type_traits>. Fully implemented, available in all language modes: * __is_constructible() * __is_nothrow_constructible() * __is_nothrow_assignable() Partially implemented, semantic analysis WIP, available as MS extensions: * __is_destructible() * __is_nothrow_destructible() llvm-svn: 199619
