    c++: Fix ({ ... }) array mem-initializer.

    Here, we were going down the wrong path in perform_member_init because of
    the incorrect parens around the mem-initializer for the array.  And then
    cxx_eval_vec_init_1 didn't know what to do with a CONSTRUCTOR as the
    initializer.  For GCC 9, let's just fix the latter issue.
