* trans-array.c (structure_alloc_comps): Make sure that the
vptr is copied and that the unlimited polymorphic _len is used
to compute the size to be allocated.
* trans-expr.c (gfc_get_class_array_ref): If unlimited, use the
unlimited polymorphic _len for the offset to the element.
(gfc_copy_class_to_class): Set the new 'unlimited' argument.
* trans.h : Add the boolean 'unlimited' to the prototype.
