All supported compilers have an acceptable <type_traits>. Commit
4cb3d46148 ("Move <type_traits> test to Cxx11RequiredFeature") made
<type_traits> support mandatory in August and no one has objected.
Remove the indirection and use namespace std directly for type_traits
members.
gcc-4.6 chokes on `static constexpr type value{};`, but accepts
`static constexpr auto value = type{};`

C++ does not require this pattern.
