RFR: JDK-8214756: SA should ignore archived java heap objects that are not in use

[Jini George]

Thank you very much, Jiangli! Yes, I did test 
open/test/hotspot/jtreg/serviceability/sa/TestHeapDumpForLargeArray.java 
after applying the changes from:

http://cr.openjdk.java.net/~redestad/8214712/jdk.00/

and it passed after this change.

Thanks,
Jini.
