Do not ignore core libraries from CHA analysis.
Do not ignore core libraries from CHA analysis.

I ran into issues with the collections library where classes and types were being finalized very late, affecting cha analysis.

class _LinkedCustomHashMap<K, V> extends _CustomHashMap<K, V> with _LinkedHashMapMixin<K, V>

abstract class _LinkedHashMapMixin<K, V> implements LinkedHashMap<K, V> {

Even though LinkedHashMap is a builtin object it can still be implemented after startup.
