    [ic] Teach CallIC about JSBoundFunction. · e57a99ce
    Benedikt Meurer authored
    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.
