peephole returns an rtx_insn

	* output.h (peephole): Strengthen return type from rtx to
	rtx_insn *.
	* rtl.h (delete_for_peephole): Likewise for both params.
	* genpeep.c (main): In generated "peephole" function, strengthen
	return type and local "insn" from rtx to rtx_insn *.  For now,
	rename param "ins1" to "uncast_ins1", adding "ins1" back as an
	rtx_insn *, with a checked cast.
	* jump.c (delete_for_peephole): Strengthen params "from", "to" and
	locals "insn", "next", "prev" from rtx to rtx_insn *.
