insn_latency takes a pair of rtx_insn

gcc/
2014-09-04  David Malcolm  <dmalcolm@redhat.com>

	* genattr.c (main): Within the prototype of insn_latency written
	out to insn-attr.h, strengthen both params from rtx to rtx_insn *.
	* genautomata.c (output_internal_maximal_insn_latency_func):
	Within the implementation of insn_latency written out to
	insn-automata.c, strengthen both params from rtx to rtx_insn *,
	eliminating a pair of checked casts.
