rtl.h (replace_label_data): Delete.

gcc/
	* rtl.h (replace_label_data): Delete.
	(replace_label): Take the old label, new label and update-nuses flag
	as direct arguments.  Return void.
	* cfgcleanup.c (outgoing_edges_match): Update accordingly.
	* rtlanal.c (replace_label): Update interface as above.  Handle
	JUMP_TABLE_DATA as a special case.  Handle JUMPs outside the
	iterator.  Use FOR_EACH_SUBRTX_PTR.
