Intrinsics, i.e. mostly constructor and prototype objects, but also things like empty and new object shape now live on a new heap-allocated JS::Intrinsics object, thus completing the long journey of taking all the magic away from the global object. This represents the Realm's [[Intrinsics]] slot in the spec and matches its existing [[GlobalObject]] / [[GlobalEnv]] slots in terms of architecture. In the majority of cases it should now be possibly to fully allocate a regular object without the global object existing, and in fact that's what we do now - the realm is allocated before the global object, and the intrinsics between both :^)
