sched-deps.c: Use rtx_insn

gcc/
2014-08-22  David Malcolm  <dmalcolm@redhat.com>

	* sched-deps.c (maybe_add_or_update_dep_1): Strengthen locals
	"elem", "insn" from rtx to rtx_insn *.
	(change_spec_dep_to_hard): Likewise.
	(get_back_and_forw_lists): Likewise for local "con".
	(sd_add_dep): Likewise for locals "elem", "insn".
	(sd_resolve_dep): Likewise for locals "pro", "con".
	(sd_unresolve_dep): Likewise.
	(sd_delete_dep): Likewise.
	(chain_to_prev_insn): Likewise for local "pro".
	(find_inc): Likewise for locals "pro", "con".
