Kraken crypto-aes/crypto-ccm have a bunch of arrays like [[], [], [], []]. The inner/empty arrays have "unknown properties" because fixArrayType cannot easily determine their type. This is at least a 10% Kraken crypto-aes/crypto-ccm IonMonkey win since it avoids some GETELEM/SETELEM IC's. JM+TI win is smaller.
