Summary: The last nail for LPP-7750?

Bugs Fixed: LPP-7750 Many warnings and errors with LZOs

Technical Reviewer: hminsky (pending)
QA Reviewer: mdemmon (pending)

Details:
     Remove the bogus methods getMerged*, which can't work because the
     compiler does not know all classes at compile time (it does not
     know the structure of the LFC-implemented classes and it does not
     know the structure of classes that will come from libraries).

     Define a new predicate inheritsClassChildren that tells whether
     the super class has (or could have, for classes we don't know)
     children.

     Fix the optimization for merging superclass children into a
     class to use the new predicate and be correct.

Tests:
     Test case from bug report
