Reverts r273305 and re-instates r273296. We needed to fix a bug in Sema::MarkVTableUsed to ensure that operator delete lookup occurs when the vtable is referenced. We already had a special case to look up operator delete when dllimport was used, but I think should really mark virtual destructors referenced any time the vtable is used. llvm-svn: 274147
