	(add_src_coords_attributes): Don't add enything if
	DECL_SOURCE_LOCATION is UNKNOWN_LOCATION.
	(dwarf2out_abstract_function): Save and clear call_arg_location,
	call_site_count and tail_call_site_count around dwarf2out_decl call.
	(gen_call_site_die): New function.

	CALL_INSNs.  Add NOTE_DURING_CALL_P var location notes even when not
	followed by any real instructions.

	argument.  Don't call cselib_preserve_only_values and
	cselib_reset_table.

	(vt_initialize): Compute argument_reg_set.  Call
	vt_add_function_parameters before processing basic blocks instead of
	afterwards.  For calls call prepare_call_arguments before calling
	cselib_process_insn.
