    c++: Don't ICE in eval_constant_of on vars with error_mark_node type
[PR125412]

    The following testcase ICEs during error recovery, because we aren't
    prepared to handle error_mark_node type.

    Fixed thusly.

            * reflect.cc (process_metafunction): If ht is error_operand_p,
            set *non_constant_p and return NULL_TREE.

            * g++.dg/reflect/pr125412.C: New test.
