predict.*: Use rtx_insn (also touches function.c and config/cris/cris.c) 

gcc/
	* predict.h (predict_insn_def): Strengthen param "insn" from rtx
	to rtx_insn *.

	* function.c (stack_protect_epilogue): Add checked cast to
	rtx_insn for now when invoking predict_insn_def.

	* predict.c (predict_insn): Strengthen param "insn" from rtx to
	rtx_insn *.
	(predict_insn_def): Likewise.
	(rtl_predict_edge): Likewise for local "last_insn".
	(can_predict_insn_p): Strengthen param "insn" from const_rtx to
	const rtx_insn *.
	(combine_predictions_for_insn): Strengthen param "insn" from rtx
	to rtx_insn *.
	(bb_estimate_probability_locally): Likewise for local "last_insn".
	(expensive_function_p): Likewise for local "insn".

	* config/cris/cris.c (cris_emit_trap_for_misalignment): Likewise for
	local "jmp", since this is used when invoking predict_insn_def.
