[PATCH 1/2] PR c++/91436 fix C++ dialect for std::make_unique fix-it hint

[Jonathan Wakely]

The std::make_unique function wasn't added until C++14, and neither was
the std::complex_literals namespace.

        * name-lookup.c (get_std_name_hint): Fix min_dialect field for
        complex_literals and make_unique entries.

        * g++.dg/lookup/missing-std-include-6.C: Don't check make_unique in

Tested x86_64-linux. OK for trunk?
