Convert nonlocal_goto_handler_labels from an EXPR_LIST to an INSN_LIST

gcc/
2014-08-28  David Malcolm  <dmalcolm@redhat.com>

	* function.h (struct rtl_data): Convert field
	"x_nonlocal_goto_handler_labels" from rtx_expr_list * to
	rtx_insn_list *.
	* rtl.h (remove_node_from_insn_list): New prototype.

	* builtins.c (expand_builtin): When prepending to
	nonlocal_goto_handler_labels, use gen_rtx_INSN_LIST rather than
	gen_rtx_EXPR_LIST.
	* cfgbuild.c (make_edges): Convert local "x" from rtx_expr_list *
	to rtx_insn_list *, and use its "insn" method rather than
	"element" method.
	* cfgrtl.c (delete_insn): Use new function
	remove_node_from_insn_list rather than
	remove_node_from_expr_list.
	(cfg_layout_initialize): Convert local "x" from rtx_expr_list *
	to rtx_insn_list *, and use its "insn" method rather than
	"element" method.
	* dwarf2cfi.c (create_trace_edges): Likewise for local "lab".
	* reload1.c (set_initial_label_offsets): Likewise for local "x".
	* rtlanal.c (remove_node_from_insn_list): New function, adapted
	from remove_node_from_expr_list.
	* stmt.c (expand_label): When prepending to
	nonlocal_goto_handler_labels, use gen_rtx_INSN_LIST rather than
	gen_rtx_EXPR_LIST.
