[lworld] RFR: JDK-8243204 add class load time checking of abstract super classes of…

[Harold Seigel]

Please review this chagne.  It adds checks of super classes of inline classes.  It checks that an inline class's super
class is  either java.lang.Object or an abstract class.  And, if abstract, checks that the super, and its super, etc.
do not have instance fields, nor synchronized instance methods, or non-empty constructors, nor constructors with args.

The fix was tested with tiers 1 - 3.
