No idea where this handler is being called. Didn't find any obvious JSC::call sites that were missed.

Fixed by Bug 152727. Source/WebCore/bindings/js/JSErrorHandler.cpp got willCallFunction and didCallFunction inspector instrumentation calls. *** This bug has been marked as a duplicate of bug 152727 ***
