rtl_data.x_nonlocal_goto_handler_labels becomes an rtx_expr_list

gcc/
2014-08-27  David Malcolm  <dmalcolm@redhat.com>

	* function.h (struct rtl_data): Strengthen field
	x_nonlocal_goto_handler_labels from rtx to rtx_expr_list *.
	* rtl.h (remove_node_from_expr_list): Strengthen second param from
	rtx * to rtx_expr_list **.

	* cfgbuild.c (make_edges): In loop over
	nonlocal_goto_handler_labels, strengthen local "x" from rtx to
	rtx_expr_list *, and use methods of the latter class to clarify
	the code.
	* cfgrtl.c (cfg_layout_initialize): Strengthen local "x" from rtx to
	rtx_expr_list *, and use methods of the latter class to clarify
	the code.
	* dwarf2cfi.c (create_trace_edges): Likewise for local "lab".
	* reload1.c (set_initial_label_offsets): Likewise for local "x".
	* rtlanal.c (remove_node_from_expr_list): Strengthen param "listp"
	from rtx * to rtx_expr_list **.  Strengthen local "temp" from rtx
	to rtx_expr_list *.  Use methods of the latter class to clarify
	the code.
