+; structures: the loop, and the inner condition.
+; Here, the condition header also branches to 2 internal nodes, which are not
+; directly a merge/exits.
+; This will require a proper header-split.
+; In addition, splitting the header makes the continue the merge of the inner
+; condition, so we need to properly split the continue block to create a
+; valid inner merge, in the correct order.
