RFR(S): 8027140: Assertion in compiler when running bigapps/Kitchensink/stability

[Roland Westrelin]

I wasn’t able to reproduce that bug or write a test case for it. Anyway, TypeKlassPtr was a subclass of TypeOopPtr before perm gen removal. TypeOopPtr::filter() had code to handle TypeKlassPtr types. When TypeKlassPtr was moved under TypePtr, this code wasn’t moved. I think it should have been and that could explain the assert.
