	PR fortran/55901
	* trans-expr.c (gfc_conv_structure): Fixed indendation.
	Using integer_zero_node now instead of explicitly
	constructing a integer constant zero node.
	(gfc_conv_derived_to_class): Add handling of _len component,
	i.e., when the rhs has a string_length then assign that to
	class' _len, else assign 0.
	(gfc_conv_intrinsic_to_class): Likewise.
