Description
JDK-8183103 fix in JDK 9 disable AVXV3 by default (it set UseAVX to 2 by default). Now that fix was pushed into JDK 10 which disables AVX3 testing: http://hg.openjdk.java.net/jdk10/hs/hotspot/rev/833f88cac52b#l7.1 There was separate bug JDK-8183390 filed for PostLoopMultiversioning so we keep it off by default until that bug is fixed.
