Add @CompatibleWith("T") to the following Subject methods to catch callsites

where developers are testing things that could never be true:

* isSameAs
* isNotSameAs
* isAnyOf
* isNoneOf

RELNOTES:
  Add the @CompatibleWith annotation from http://errorprone.info to
  isSameAs, isNotSameAs, isAnyOf, and isNoneOf in Subject, so users of the Error
  Prone compiler can check their tests.
