define_bypass guard functions take a pair of rtx_insn

	* genautomata.c (output_internal_insn_latency_func): When writing
	the function "internal_insn_latency" to insn-automata.c,
	strengthen params "insn" and "insn2" from rtx to rtx_insn *, thus
	allowing the optional guard function of (define_bypass) clauses to
	expect a pair of rtx_insn *, rather than a pair of rtx.
	(output_insn_latency_func): When writing the function
	"insn_latency", add an "uncast_" prefix to params "insn" and
	"insn2", reintroducing "insn" and "insn2" as rtx_insn * locals
	using checked casts from the params, thus enabling the above
	change to the generated "internal_insn_latency" function.
