Make computation of arguments for raw types lazy
See how we translate raw types to Kotlin model: RawType(A) = A<ErasedUpperBound(T1), ...> ErasedUpperBound(T : G<t>) = G<*> // UpperBound(T) is a type G<t> with arguments ErasedUpperBound(T : A) = A // UpperBound(T) is a type A without arguments ErasedUpperBound(T : F) = UpperBound(F) // UB(T) is another type parameter F Stack overflow happens with the following classes: class A<X extends B> // NB: raw type B in upper bound class B<Y extends A> // NB: raw type A in upper bound when calculating raw type for A, we start calculate ErasedUpperBound(Y), thus starting calculating raw type for B => ErasedUpperBound(X) => RawType(A), so we have SOE here. The problem is that we calculating the arguments for these raw types eagerly, while from the definition of ErasedUpperBound(Y) we only need a type constructor of raw type B (and the number of parameters), we don't use its arguments. The solution is to make arguments calculating for raw types lazy #KT-16528 Fixed
