Implicitly induced noSuchMethod forwarders cannot eliminate primitive
equality: They are not generated at all if they would override an
explicit member declaration (here: `Object.hashCode` and `Object.[]`).
Hence, the classes `Secret...` that we used to have (which were intended
to do just that) were simply compile-time errors, and hence those
classes and the locations where they were used are being removed in
this CL.
