RFR: 8138659: Speed up InstanceKlass subclass discrimination

[Coleen Phillimore]

Kim,

This looks *very* nice.   Thank you for doing this:

+    return static_cast<InstanceMirrorKlass*>(k);


For bonus points can you change this to a static_cast<>  ???

   // Casting from Klass*
   static InstanceKlass* cast(Klass* k) {
     assert(k == NULL || k->is_klass(), "must be");
     assert(k == NULL || k->oop_is_instance(), "cast to InstanceKlass");
     return (InstanceKlass*) k;
   }

I don't have to see it though.

Thanks!
Coleen
