SI-8040 Xlint enables unused warnings
`-Ywarn-unused-import` is deprecated in favor of `-Ywarn-unused:imports`.
`-Xlint` does not yet enable `-Ywarn-unused:patvars`.
But the default for `-Ywarn-unused` is everything, including `patvars`.
So `-Xlint:unused` is the populist option, `-Ywarn-unused` more exclusive.
Tests are fixed by narrowing scope of `-Xlint` when specified.
