X87: [Interpreter] Collect type feedback for calls in the bytecode handler.

Browse Source 
port fd420203ec (r37700)

  original commit message:
  Collect type feedback in the call bytecode handler. The current
  implementation only collects feedback for JS function objects. The other
  objects and Array functions do not collect any feedback. They will be
  marked Megamorphic.
