    c++: non-static member, array bound, sizeof [PR93314]

    N2253 allowed referring to non-static data members without an object in
    unevaluated operands like that of sizeof, but in a constant-expression
    context like an array bound or template argument within such an unevaluated
    operand we do actually need a value, so that permission cannot apply.

            * semantics.c (finish_id_expression_1): Clear
cp_unevaluated_operand
            for a non-static data member in a constant-expression.
