[jdk11u-dev] RFR: 8366125: [11u] Test compiler/loopopts/TestRangeCheckPredicatesControl.java fails OOM

[SendaoYan]

Hi all,

On ours linux-x64 machine, `-Xmx256M -XX:+UnlockExperimentalVMOptions -XX:+UseZGC` can not start JVM because of OOM. I think it's not a JVM bug in jdk11u, I think we should increase the max heap size to make test run normally after [JDK-8251949](https://bugs.openjdk.org/browse/JDK-8251949). The `-Xmx256m` was introduced by [JDK-8251949](https://bugs.openjdk.org/browse/JDK-8251949) only for jdk11u. So this PR will only for jdk11u also.

Change has been verified locally, test-fix only, ro risk.
