    Source/JavaScriptCore:
    
    Implement support for stack traces on exception objects.  This is a rewrite
    of the core portion of the last stack walking logic, but the mechanical work
    of adding the information to an exception comes from the original work by
    Juan Carlos Montemayor Elosua.
