TypeRef type wraps around another type and it was used to represent a graph of recursive types. After [0], the only use of TypeRef is for TypeParameter.bound which may indirectly reference the same TypeParameter. This change replaces TypeParameter.bound with TypeParameter.owner and removes TypeRef entirely. Various parts of the VM no longer need to handle and support TypeRefs. TypeParameter.owner can reference a FunctionType, Class, or, as an optimization, it can be set to null in order to share class type parameters among different classes. With the exception of the 'TypeParameter.owner' back pointer, VM types are now not recursive and can be visited without additional tracking. Caveats: * Generic FunctionType cannot be cloned in a shallow way: when copying a FunctionType, type parameters should be cloned too and their owners should be updated. For that reason, a mapping between 'from' and 'to' function types (FunctionTypeMapping) is maintained during type transformations such as InstantiateFrom. FunctionType::Clone is used instead of Object::Clone where appropriate. * When testing types for subtyping and equivalence, mapping between function types is passed to make sure type parameters belong to the equivalent function types. * IL serializer needs to serialize function types as a whole before serializing any types potentially pointing into the middle of a function type (such as return type 'List<Y0>' pointing into the middle of a function type 'List<Y0> Function<Y0>()').
