RFR(XS) 8177856: [AOT] EliminateRedundantInitializationPhase is not working

[Igor Veresov]

EliminateRedundantInitializationPhase was not updated to take into the account the change in the Constant hierarchy.

Webrev: http://cr.openjdk.java.net/~iveresov/8177856/webrev.00/

I’d like to get this in 9.

Thanks,
igor
