Cristiano Calcagno 434cfbfb15 [eradicate] Add support for new annotation @PropagatesNullable ... Summary: One limitation of Eradicate is that certain nullability patterns are not expressible using simply the `Nullable` annotation. One such pattern is using the knowledge that a function returns null when passed null, but returns an object otherwise. The annotation `PropagatesNullable` is a variant of `Nullable` applied to parameters when their value propagates to the return value. A method annotated ``` B m(PropagatesNullable A x) { return x == null ? x : B(x); } ``` indicates that `m` returns null if `x` is null, or an object of class `B` if the argument is not null. Examples with multiple parameters are in the test cases. This diff builds some infrastructure for annotation transformers: the example above represents the identity function on nullability annotations.
