RFR: 8266642: improve ResolvedMethodTable hash function

[Denghui Dong]

JDK-8249719 has fixed the bad hash function problem, however, when there are a large number of classes with the same name, there are still performance problems.
Add the address of the corresponding ClassLoaderData as a factor of hash can solve the problem.
