https://openjdk.org/jeps/460 is still an incubator so I won't add this to the jdk22 milestone.

In the above test job, other vector tests, for example jdk_vector_int128_j9_0, passed but only 2 operations were reported as vectorized. There are many more operations that should be vectorized.

I could reproduce the failure with aarch64 linux. It is not an amac specific problem.
https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder/37206/

15:23:58  Eclipse OpenJ9 VM (build master-62a8124490e, JRE 22 Linux aarch64-64-Bit Compressed References 20240109_6 (JIT enabled, AOT enabled)

I could also reproduce it with x86 linux.

I tried a simple program with the above aarch64 linux VM. Surprisingly, vectorization did not happen. It gets vectorized when JDK21 VM is used.

       //  ADD 
       for (int i = 0; i < a.length; i += SPECIES.length()) {
          IntVector va = IntVector.fromArray(SPECIES, a, i);
          IntVector vb = IntVector.fromArray(SPECIES, b, i);
          IntVector vc = va.add(vb);
          vc.intoArray(c, i);
       }

I attach the trace log below. @gita-omr can you please take a look?
