(The exact change is slightly different in some cases, like when using custom subjects, but it's still a migration from named(...) to assertWithMessage(...).)
Or, in one case, migrate from calling this.named(...) to overriding actualCustomStringRepresentation().
named(...) is being removed.
This CL may modify the failure messages produced, but all the old information will still be present.
