	of GFC_DECL_SAVED_DESCRIPTOR by testing for DECL_LANG_SPECIFIC

	(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

	'mold_expr' was already declared. Use it instead of 'arg'. Do

	finalization blocks to the main block.
	(gfc_trans_arrayfunc_assign): Use gfc_assignment_finalizer_call

	function results using gfc_finalize_tree_expr.
