libc++ implements its' hash objects as deriving from std::unary_function, and the tests test for that. STL @ MS pointed out that the standard doesn't requie these objects to derive from unary_function, and so the tests should not require that either. Change the tests to check for the embedded typedefs - which ARE required. No change to the library.
