dwarf2out.c (dwarf_op): Renamed to ...

	* dwarf2out.c (dwarf_op): Renamed to ...

	(convert_descriptor_to_mode, scompare_loc_descriptor,
	minmax_loc_descriptor, typed_binop, mem_loc_descriptor,
	implicit_ptr_descriptor, optimize_one_addr_into_implicit_ptr): Adjust

	(dwarf_AT, dwarf_TAG): New functions.
	(check_die): Disallow DW_AT_call_all_calls next to
	DW_AT_GNU_all_call_sites.
	(gen_call_site_die): Use dwarf_TAG and dwarf_AT with DWARF 5 tag
	and attributes instead of the corresponding GNU tag and attributes.
	(gen_subprogram_die): Likewise.  Emit call site information even
	for -gdwarf-5 -gstrict-dwarf.  Replace DW_AT_GNU_defaulted with
	DW_AT_defaulted in comment.
	(resolve_addr): Handle DW_AT_call_origin attribute on
