RFR(XS): 8241009: CommandLineFlagComboNegative.java fails after JDK-8240563

[Yumin Qi]

Hi, please review

   Bug:https://bugs.openjdk.java.net/browse/JDK-8241009 
<https://bugs.openjdk.java.net/browse/JDK-8241009>
   Webrev: http://cr.openjdk.java.net/~minqi/8241009/webrev/

   The vmoptions from jtreg still affect the launched processes and mess 
up the parameters for launched java processes in the test.
   Fix skip the test if -XX:-UseCompressedOops or 
-XX:-UseCompressedClassPointers in jtreg vmoptions (or javaoptions).

   Tests: tested with explicitly set -XX:-UseCompressedOops or 
-XX:-UseCompressedClassPointers or both in jtreg vmoptions.
   tier1,2,4,7 test pending.

Thanks
Yumin
