cfgloopanal.c: Use rtx_insn

gcc/
2014-08-21  David Malcolm  <dmalcolm@redhat.com>

	* cfgloopanal.c (num_loop_insns): Strengthen local "insn" from
	rtx to rtx_insn *.
	(average_num_loop_insns): Likewise.
	(init_set_costs): Likewise for local "seq".
	(seq_cost): Likewise for param "seq", from const_rtx to const
	rtx_insn *.
