Log:
	* decl.c (maybe_pad_type): Try to get a form of the type with integral
	mode even if the alignment is not a factor of the original size.  But
	make sure to create the inner field with the original size.  Reorder.
	* trans.c (addressable_p) <COMPONENT_REF>: Treat the field of a padding
	record as always addressable.
	* utils.c (convert): Deal specially with conversions between original
	and packable versions of a record type.
	* utils2.c (build_binary_op) <MODIFY_EXPR>: Be more restrictive when
	recognizing an assignment between padded objects.
