RFR (XS) 8208100: compiler/graalunit/JttLangMathALTest.java times out intermittently on Linux-X64

[Doug Simon]

When running these tests on Graal tip against JDK 11, I get:

mx --java-home=/Library/Java/JavaVirtualMachines/jdk-11.jdk/Contents/Home unittest org.graalvm.compiler.jtt.lang.Math
...
10 longest running test classes:
     21.115 ms    org.graalvm.compiler.jtt.lang.Math_log10
     11.921 ms    org.graalvm.compiler.jtt.lang.Math_log
     10.460 ms    org.graalvm.compiler.jtt.lang.Math_sqrt
      3.525 ms    org.graalvm.compiler.jtt.lang.Math_pow

         84 ms    run0(org.graalvm.compiler.jtt.lang.Math_sin)

All seems as expected.

I wanted to try it against JDK tip but https://bugs.openjdk.java.net/browse/JDK-8209301 means GitHub Graal cannot be compiled against the latest JDK:

/Users/dsimon/graal/graal/compiler/src/jdk.tools.jaotc/src/jdk/tools/jaotc/AOTCompiledClass.java:77: error: cannot find symbol
            this.metadataName = type.isAnonymous() ? "anon<" + classId + ">" : type.getName();
                                    ^
  symbol:   method isAnonymous()
  location: variable type of type HotSpotResolvedObjectType
1 error

To fix this, AOTCompiledClass.java will either have to use reflection to access HotSpotResolvedObjectType.isAnonymous[Unsafe]Anonymous or a jdk12 versioned project will have to be added.
