[analyzer] Allow TrackConstraintBRVisitor to work when the value it’s tracking is not live in the last node of the path
We always register the visitor on a node in which the value we are tracking is live and constrained. However,
the visitation can restart at a node, later on the path, in which the value is under constrained because
it is no longer live. Previously, we just silently stopped tracking in that case.
