class CollectSuperCalls
extends MiniPhase

Collect all super calls to trait members.

For each super reference to trait member, register a call from the current class to the owner of the referenced member.

This information is used to know if it is safe to remove a redundant mixin class. A redundant mixin class is one that is implemented by another mixin class. As the methods in a redundant mixin class could be implemented with a default abstract method, the redundant mixin class could be required as a parent by the JVM.
