Don't understand the logic here, What is the significance of ScalaATTR? What happens with Scala2 classfiles?

Is there are way both isAbsent and isAccessibleFrom can be true? Should there be?

This is similar to scala/scala#5952, we do not need to parse artifact classfiles (that is, classfiles produced by scalac or dotty that do not contain pickling information), so we discard them as soon as possible. This fixes various IDE crashes when trying to complete packages such as "scala."
