        * trans-expr.c (gfc_class_len_or_zero_get): Add function to return a
        constant zero tree, when the class to get the _len component from is
        not unlimited polymorphic.
        (gfc_copy_class_to_class): Use the new function.
        * trans.h: Added interface of new function gfc_class_len_or_zero_get.
