Each time a transition is added to a hidden class, the whole transitions array must be copied, which causes poor performance in some circumstances. This change limits the maximum size of the transition array, avoiding this behavior in the pathological case. For example, this improves the performance of the EtchMark benchmark by nearly 60%.
