In `AnnotatedTypeBaseImpl`, a `decl` field is declared, referring to the declaration that the AnnotatedType is from. However, this field is not used anywhere except passing to constructors of other implementations; it's not used in debug messages (unlike in `TypeAnnotation`), not involved in equality checks. Since these implementations are not serializable, we can safely remove the decl field from the implementations. All 1048 java/lang tests pass on my machine.
