libstdc++: Simplify numeric_limits<__max_size_type>
If __int128 is supported then __int_traits<__int128> is guaranteed to be
specialized, so we can remove the preprocessor condition inside the
std::numeric_traits<__detail::__max_size_type> specialization. Simply
using __int_traits<_Sp::__rep> gives the right answer.

libstdc++-v3/ChangeLog:
* include/bits/max_size_type.h (numeric_limits<__max_size_type>):
Use __int_traits unconditionally.
