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

	* resource.h (clear_hashed_info_for_insn): Strengthen param from
	rtx to rtx_insn *.
	(incr_ticks_for_insn): Likewise.
	(init_resource_info): Likewise.

	* resource.c (init_resource_info): Likewise.
	(clear_hashed_info_for_insn): Likewise.
	(incr_ticks_for_insn): Likewise.

	* reorg.c (delete_scheduled_jump): Strengthen param "insn" from
	rtx to rtx_insn *.
	(steal_delay_list_from_target): Use methods of "seq".
	(try_merge_delay_insns): Use methods of "merged_insns".
	(update_block): Strengthen param "insn" from rtx to rtx_insn *.
	(reorg_redirect_jump): Likewise for param "jump".
