Always call finalizer for stack classes. Checking for the number of destructors of the class type is not sufficient: we may be holding a derived class with a destructor. Fixes: run/auto_07

module arrays3;

void main()
{
    int[] arr;
    {arr = new int[25];}
    {assert(arr.length == 25);}
    {arr.length = arr.length + 5;}
    {assert(arr.length == 30);}
}
