> Simplifier does not optimize ldvfnslot->ldfnslot when VTable load instruction has
been simplified before (ldvtable->getvtable). The attached patch enables such optimization
thus allowing further simpification of virtual call to a direct call.
> The patch has been tested on Win32/debug/SPECjbb2005 only.
