/// @assertion We allow tearing off named constructors.
///
/// If [C] denotes a class declaration and [C.name] is the name of a constructor
/// of that class, we allow you to tear off that constructors as:
///
///  C.name, or
///  C<typeArgs>.name
///
/// just as you can currently invoke the constructor as [C.name(args)], or
/// [C<typeArgs>.name(args)].
///
/// @description Checks that tearing off named constructor is allowed for a
/// non-generic class.
