* iresolve.cc (gfc_resolve_transfer): Emit a TODO error for
unlimited polymorphic mold.
* trans-expr.cc (gfc_resize_class_size_with_len): Use the fold
even if a block is not available in which to fix the result.
(trans_class_assignment): Enable correct assignment of
character expressions to unlimited polymorphic variables using
lhs _len field and rse string_length.
* trans-intrinsic.cc (gfc_conv_intrinsic_storage_size): Extract
the class expression so that the unlimited polymorphic class
expression can be used in gfc_resize_class_size_with_len to
obtain the storage size for character payloads. Guard the use
of GFC_DECL_SAVED_DESCRIPTOR by testing for DECL_LANG_SPECIFIC
to prevent the ICE. Also, invert the order to use the class
expression extracted from the argument.
(gfc_conv_intrinsic_transfer): In same way as 'storage_size',
use the _len field to obtaining the correct length for arg 1.
Add a branch for the element size in bytes of class expressions
with provision to make use of the unlimited polymorphic _len
field. Again, the class references are explicitly identified.
'mold_expr' was already declared. Use it instead of 'arg'. Do
not fix 'dest_word_len' for deferred character sources because
reallocation on assign makes use of it before it is assigned.
