RFR: 8337548: Dumping static archive passes is_superclass true for interfaces

[Coleen Phillimore]

Save the setting of is_superclass in the DETECT_CIRCULARITY placeholder entry with the class name in case handle_parallel_super_load is needed.  This corrects the is_superclass parameter passed to resolve_with_circularity_detection, which is then used by CDS code.

Tested with tier1-7 (in progress).
