…atsakis Don't keep the possibly initialized flow around longer than needed The possibly initialized flow isn't used after liveness is computed, so don't keep it around. Locally this is about a 10% time win for tuple-stress (which is spending a lot of time calculating flows now that it's not spending so much on liveness). r? @nikomatsakis
