* dwarf2read.c (partial_die_full_name): Record DW_FORM_ref_addr in

	attr.u.unsnd instead of attr.u.addr.
	(read_attribute_value) Ditto for cases DW_FORM_ref_addr,
	DW_FORM_ref1, DW_FORM_ref2, DW_FORM_ref4, DW_FORM_reg8,
	DW_FORM_ref_udata.
	(dump_die_shallow): Update cases DW_FORM_ref_addr,
	DW_FORM_ref1, DW_FORM_ref2, DW_FORM_ref4.  Add cases DW_FORM_ref8,
	DW_FORM_ref_udata.
	(dwarf2_get_ref_die_offset): Use DW_UNSND for reference attributes.
