/**
* @assertion Let [G] be a generic class or parameterized type alias with formal
* type parameter declarations [F1] .. [Fk] containing formal type parameters
* [X1] .. [Xk] and bounds [B1] .. [Bk]. We say that the formal type parameter
* [Xj] has a simple bound when one of the following requirements is satisfied:
* [Bj] is omitted.
* [Bj] is included, but does not contain any of [X1] .. [Xk]. If [Bj] contains
* a type [T] on the form qualified (for instance, [C] or [p.D]) which denotes a
* generic class or parameterized type alias [G1] (that is, [T] is a raw type),
* every type argument of [G1] has a simple bound.
* @description Checks that instantiate-to-bounds works as expected for:
* [class A<X>], [class B<X extends A?, Y extends X>?]
* @author iarkh@unipro.ru
