    c++: fix for printing std::meta::info [PR124489]

    When printing the diagnostics in this test, we're saying
    "constexprstd::meta::info dm" which misses a space.  We
    should use pp_cxx_ws_string which does pp_c_maybe_whitespace
    when printing "std::meta::info".

            PR c++/124489

    gcc/cp/ChangeLog:

            * error.cc (dump_type) <case NULLPTR_TYPE>: Use pp_cxx_ws_string
            instead of pp_string.
