	* dwarf2out.h (enum dw_val_class): Add dw_val_class_loclistsptr.
	* dwarf2out.c (struct dw_loc_list_struct): Change emitted field
	from bool to 1-bit uchar bitfield.  Add num_assigned and
	offset_emitted bitfields.
	(dw_val_equal_p): Compare v.val_lbl_id rather than v.val_unsigned
	for dw_val_class_lineptr and dw_val_class_macptr.  Handle
	dw_val_class_loclistsptr.
	(new_addr_loc_descr): Fix up formatting.

	(add_AT_loclistsptr): New function.
	(AT_lbl): Allow dw_val_class_loclistsptr.
	(print_dw_val, attr_checksum, attr_checksum_ordered, same_dw_val_p):

	(size_of_die): For dw_val_class_loc_list -gsplit-dwarf -gdwarf-5

	dwarf_split_debug_info AT_index handling.  Handle
	dw_val_class_loclistsptr.
	(value_format): Return DW_FORM_loclistsx for dw_val_class_loc_list

	For dw_val_class_loc_list call output_loc_list_offset rather than

	(init_sections_and_labels): For -gdwarf-5 use .debug_loclists
	or .debug_loclists.dwo section name for debug_loc_section.
	(resolve_addr_in_expr): Formatting fix.
	(index_location_lists): Likewise.
	(dwarf2out_finish): If there are any location lists, for
	-gsplit-dwarf -gdwarf-5 add DW_AT_loclists_base attribute.  Call
	index_location_lists only if have_location_lists.  Call
	assign_location_list_indexes for -gsplit-dwarf -gdwarf-5.  Emit
	.debug_loclists{,.dwo} section header for -gdwarf-5, for -gdwarf-5
	-gsplit-dwarf also emit offset table.
