type_traits: type_traits_test bug?

Intel C++ uncovered the following with a warning:

------------------------
    typedef int& r_type;
    typedef const r_type cr_type;
------------------------
type_traits_test.hpp(278): warning #21: type qualifiers are meaningless in
this declaration
  typedef const r_type cr_type;
          ^
------------------------

I wonder if we've been testing the right things?

I changed it to:

    typedef int const& cr_type;

Everything seems to continue to pass.
On the other hand, the pragmas used to disable warnings with MSVC suggest
that this was intentional. Was it? A comment would be a big help, here.
