    c++: constinit diagnostic regression [PR120506]

    In r16-57 I thought it was unnecessary to mention incomplete initialization
    after another diagnostic, but actually it's useful elaboration.

            PR c++/120506

    gcc/cp/ChangeLog:

            * constexpr.cc (cxx_eval_outermost_constant_expr): Always check
            CONSTRUCTOR_NO_CLEARING.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp2a/constinit21.C: New test.
