   * Date:    13 Oct 2003
   * SUMMARY: Make our f.caller property match IE's wrt f.apply and f.call
   * See http://bugzilla.mozilla.org/show_bug.cgi?id=222029
   *
   * Below, when gg calls f via |f.call|, we have this call chain:
   *
   *          calls                                  calls
   *   gg() --------->  Function.prototype.call()  --------->  f()
   *
   *
   * The question this bug addresses is, "What should we say |f.caller| is?"
   *
   * Before this fix, SpiderMonkey said it was |Function.prototype.call|.
   * After this fix, SpiderMonkey emulates IE and says |gg| instead.
   *
