Fix support for anon. inner with object initializer and further nested anon. types

[eric-milles]

Consider the following:

interface AA {}
interface BB<T> {}
interface CC<T extends AA> {}
interface DD<T extends AA & BB> {}

new AA() {
  {
    new BB() {}
  }
  public void whatever() {
    new BB() {}
    new CC() {
      {
        new DD() {}
      }
    }
  }
}

Anonymous inner types nested within the object initializers of anonymous inner types. Generics probably don't matter.
