[nestmates] Implement the following rules for hidden nestmate classes
- Lookup::defineHiddenClass can optionally add a hidden class to
  the nest of the lookup class
- Hidden classes cannot participate in static nest membership as
  they do not have names.  NestHost/NestMembers attributes on
  hidden classes are ignored
- After validation, a class with a bad NestHost belongs to a nest
  consisting only of itself (i.e. fallback to pretend that the
  attribute was not present)
- After validation of the asymmetric NH/NM attributes (or after
  a bad NH is thrown away),  access control effects of nesting
  structure are applied uniformly across the nest
- A hidden class belongs to one nest determined at runtime.  If added
  as a member to the nest of a lookup class LC, then the runtime nest
  host of the hidden class HC has the same runtime nest host as LC:
  a) LC has no NH attribute, LC is the runtime nest host of HC
  b) LC has a valid NH attribute (H), H is the runtime nest host of HC
  c) LC has a bad NH attribute, LC becomes the runtime nest of LC
- LC::getNestHost == HC::getNestHost and
  LC::getNestMembers == HC::getNestMembers
