RFR(XS): 8240546: runtime/cds/appcds/TestZGCWithCDS.java fails with Graal

[Yumin Qi]

Hi,

   Can I have your review on

   Bug: https://bugs.openjdk.java.net/browse/JDK-8240546

   Webrev: http://cr.openjdk.java.net/~minqi/8240546/webrev/

   Summary: TestZGCWithCDS failed graal on ZGC since Graal does not  
work with ZGC. Fixed in test code to skip when Graal enabled.


   Thanks

   Yumin
