Refined crash avoidance related to self type tests in anonymous classes
as introduced for #576. Now it really only excludes anonymous classes.
Suddenly, this works:
override def equals(other: Any) = other match {
case _: this.type => true
case _ => false
}
Who will be the first to roll out some reference equality in the
this.type style? No review.
