When growing an array, we're checking if element type is nullable.
The problem is that 'null is! T' is true for legacy types T
(other than top types and Null), so it throws for List<int*>.
In order to be able to grow arrays with all element types which can
hold null (including legacy element types) this test is changed to
null as T;
which throws type error if T cannot hold null.
