[Bug classpath/29086] AbstractCollection.toArray(T[]) has 'unreachable' code

I think that (T) cast is not a no-op.
T is a type parameteer of toArray.
However the container is parameterized by E, a different type variable.
Our iterator has type Iterator<E>, so the result of
itr.next() has type E.  So, an explicit cast is still needed.
We can get a ClassCastException if the user passes in an array whose
type is not compatible with E.
