Java HotSpot(TM) Client VM warning: Performance bug: SystemDictionary lookup_count=21831450 lookup_length=1275207287 average=58.411479 load=5.572844

I've never seen such warning before, and not sure that it relates to jvmci, but it happened in jvmci PIT, so targeting it to hs/compiler

relates to

JDK-8160577 verify_lookup_length is defined and implemented in BasicHashtable, but only used by SharedDictionary
