[PATCH 114/236] sel-sched.c: Use rtx_insn


gcc/
	* sel-sched.c (substitute_reg_in_expr): Strengthen local
	"new_insn" from rtx to rtx_insn *.
	(create_insn_rtx_with_rhs): Likewise for return type and for local
	"insn_rtx".
	(create_insn_rtx_with_lhs): Likewise.
	(create_speculation_check): Likewise for local "insn_rtx".
	(implicit_clobber_conflict_p): Likewise for local "insn".
	(get_expr_cost): Likewise.
	(emit_bookkeeping_insn): Likewise for local "new_insn_rtx".
	(move_cond_jump): Likewise for locals "next", "prev", "link",
	"head", "from", "to".
