genautomata.c cleanup 

	* genattr.c (main): Change 'rtx' to 'rtx_insn *' in prototypes of
	'insn_latency', 'maximal_insn_latency', 'min_insn_conflict_delay'.
	* genautomata.c (output_internal_insn_code_evaluation): Simplify.
	Move handling of non-insn arguments inline into the sole user:
	(output_trans_func): ...here.
	(output_min_insn_conflict_delay_func): Change 'rtx' to 'rtx_insn *'
	in emitted function prototype.
	(output_internal_insn_latency_func): Ditto.  Simplify.
	(output_internal_maximal_insn_latency_func): Ditto.  Delete
	always-unused argument.
	(output_insn_latency_func): Ditto.
	(output_maximal_insn_latency_func): Ditto.
