    c++: op=3D=3D defaulted outside class [PR110084]

    defaulted_late_check is for checks that need to happen after the class =
is
    complete; we shouldn't call it sooner.

            PR c++/110084

    gcc/cp/ChangeLog:

            * pt.cc (tsubst_function_decl): Only check a function defaulted
            outside the class if the class is complete.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp2a/spaceship-synth-neg3.C: Check error message.
            * g++.dg/cpp2a/spaceship-eq16.C: New test.
