* trans-array.c (structure_alloc_comps): On deallocation of
class components, reset the vptr to the declared type vtable
and reset the _len field of unlimited polymorphic components.
*trans-expr.c (gfc_find_and_cut_at_last_class_ref): Bail out on
allocatable component references to the right of part reference
with non-zero rank and return NULL.
(gfc_reset_vptr): Simplify this function by using the function
gfc_get_vptr_from_expr. Return if the vptr is NULL_TREE.
(gfc_reset_len): If gfc_find_and_cut_at_last_class_ref returns
NULL return.
