Tests doesn't work for AIX

[sophia-guo]

JDK8:
runtime/7110720/Test7110720.sh.Test7110720
compiler/6894807/IsInstanceTest.java.IsInstanceTest

doesn't work for AIX
https://github.com/adoptium/jdk8u/blob/master/hotspot/test/compiler/6894807/Test6894807.sh#L23-L43
https://github.com/adoptium/jdk8u/blob/master/hotspot/test/runtime/7110720/Test7110720.sh#L30-L59

Need to exclude, or need to update upstream testcase.

compiler/8004051/Test8004051.java
gc/g1/TestHumongousCodeCacheRoots.java.TestHumongousCodeCacheRoots:

Both tests use -client option. * @run main/othervm -Xcomp -client Test8004051 https://github.com/adoptium/jdk8u/blob/master/hotspot/test/compiler/8004051/Test8004051.java#L31

runTest("-client", baseArguments); , https://github.com/adoptium/jdk8u/blob/master/hotspot/test/gc/g1/TestHumongousCodeCacheRoots.java#L139

Looks like AIX JDK8 doesn't support this option and tests got error:

18:57:04  Unrecognized option: -client
18:57:04  Error: Could not create the Java Virtual Machine.
18:57:04  Error: A fatal exception has occurred. Program will exit
