Unused methods removed, class renamed
Incomplete analysis results are available for light class generation

 If we have the following classes

 class A // Kotlin
 class B extends A {} // Java
 class C : B() // Kotlin

 The analysis runs into infinite recursion, because C needs all members of B (to compute overrides),
 and B needs all members of A, and A is not available from KotlinCacheManager.getDeclarationsFromProject() -- it is being computed right now,
 so the analysis runs again...

 Our workaround is:
  * when analysis starts put its trace into user data on the project
  * when a light class is about to generate a stub, it requests a trace, and if there is such an incomplete trace, it is returned
  * the logic of TopDownAnalyzer that works in descending order (down the class hierarchy) guarantees that all the superclasses are already processed
