This addresses the odd performance cliff, where the CallIC tracks known JSFunction targets, but goes MEGAMORPHIC when it sees a JSBoundFunction target. With this fix in place the micro-benchmark on the bug goes from arrowCall: 82 ms. boundCall: 234 ms. to arrowCall: 81 ms. boundCall: 80 ms. so Function#bind doesn't cause any additional overhead anymore.
