Monkey: hoist [[Has Property]] from loops over dense arrays
In bug 462300 comment 92, dmandelin proposed hoisting [[HasProperty]] checks from array loops. In JM, this would reduce the overhead of Array#forEach (and probably all other array extras containing the same core loop) by about 10% to 15%. I don't know how much the same optimization would gain us in IonMonkey.
Whiteboard: [js:t] → [js:t][ion:t]
