RFR: 8210943: Hiding of inner classes not resolved properly

[Hannes Wallnöfer]

Please review:

Bug: https://bugs.openjdk.java.net/browse/JDK-8210943
Webrev: http://cr.openjdk.java.net/~hannesw/8210943/webrev.00/

AccessibleMembersLookup#lookupAccessibleMembers adds all nested classes returned by Class.getClasses(), but these may contain inherited classes that are shadowed and thus not visible from the current class. The solution is to make sure we use the first inner class with any given name.

Thanks,
Hannes
