        Bug 23551: Crash on page load with profiler enabled and running
        <https://bugs.webkit.org/show_bug.cgi?id=23551>
        <rdar://problem/6529521>

        Interpreter::execute(FunctionBodyNode*, ...) calls Profiler::didExecute()
        with a stale CallFrame. If some part of the scope chain has already been
        freed, Profiler::didExecute() will crash when attempting to get the lexical
        global object. The fix is to make the didExecute() call use the caller's
        CallFrame, not the one made for the function call. In this case, the
        willExecute() call should also be changed to match.

        Since this occurs in the actual inspector JS, it is difficult to reduce.
        I couldn't make a layout test.

        (JSC::Interpreter::execute):
