RFR: 8356551: Javac rejects receiver parameter in constructor of local class in early construction context

[Archie Cobbs]

Consider a class like this:

class Outer {
  Outer() {
    class Local {
      Local(Outer Outer.this) {  // "receiver parameter"
      }
    }
    super();
  }
}

Normally, a reference to `Outer.this` appearing anywhere in `Local` would generate an error because `Local` is defined in an early construction context of `Outer`. But in the above example, `Outer.this` is a "receiver parameter", which is the relatively obscure mechanism by which type annotations can be added to the outer instance (JLS §8.4).

This is allowed, even though the outer instance is otherwise inaccessible here. However, the compiler was reporting an error. This PR adds an exception for receiver parameters to the illegal early access check. It also adds a missing bug ID to the regression test.

 - Update copyrights.
 - Allow prologue references to "Foo.this" when appearing as a receiver parameter.
