Prevent dependent packages from commiting type piracy easily and unintentionally when defining an AbstractTrees trait for all subtypes of a type. Specifically: the bottom type,
Union{}
, is a subtype of each type, so add a method for the bottom type for each AbstractTrees trait. This method will take precedence over sane methods in dependent packages, thus preventing spurious type piracy.
