C++20 removes a number of std::allocator members that have correct

Several extensions including __gnu_cxx::hash_map and tr1 containers are
no longer usable with std::allocator in C++20 mode. They need to be
updated to use __gnu_cxx::__alloc_traits in a follow-up patch.
Tested powerpc64le-linux, committed to trunk.
I forgot to add the [[deprecated]] attribute to the members in C++17
mode, I'll do that when I fix the extensions and TR1 containers to
work in C++20 mode again.
