(finish_struct): Add ATTRIBUTES argument, call decl_attributes and set DECL_PACKED from TYPE_PACKED.

(finish_struct): Add ATTRIBUTES argument, call decl_attributes and set
DECL_PACKED from TYPE_PACKED.
(finish_enum): Add ATTRIBUTES argument, call decl_attributes, and make enum
narrow if TYPE_PACKED.
