[10] RFR(S): 8192989: runtime/appcds/javaldr/ArrayTest.java crashes with assert(k->is_instance_klass())

[Calvin Cheung]

bug: https://bugs.openjdk.java.net/browse/JDK-8192989

For JDK10, we're going for a simple and safe fix by not processing array 
classes found in a class list during CDS dump time.
We'll revisit the dumping of array classes in JDK11.

Testing:
     hs-tier1, hs-tier2 on 64-bit platforms (linux, macosx, windows, sparc).

thanks,
Calvin
