Still an issue:
Created preheader block for loop 2
;; 3 loops found, 3 levels
;;
;; Loop 0:
;;  header -1, latch -2, pre-header -1
;;  depth 0, level 3, outer -1
;;  nodes: -1 0 1 4 2 3 8 7 5 6 -2
;;
;; Loop 1:
;;  header 3, latch 2, pre-header -1
;;  depth 1, level 2, outer 0
;;  nodes: 3 2 6 1 7 8 4
;;
;; Loop 2:
;;  header 7, latch 8, pre-header -1
;;  depth 2, level 1, outer 1
;;  nodes: 7 8 6
;; 0 succs { 3 }
;; 1 succs { 4 2 }
;; 4 succs { 7 }
;; 2 succs { 3 }
;; 3 succs { 1 5 }
;; 8 succs { 7 }
;; 7 succs { 5 6 }
;; 5 succs { -2 }
;; 6 succs { 2 8 }
