virtual/stress/PingPon fails on win-arm64

[Sergey Nazarkin]

Hi!

We have encountered an issue with the PingPong [1] stress test with JDK21 (and JDK 25) run on Win-ARM64, other platforms seem unaffected. I haven't found any record of this issue (except valhalla related [2]), so I'd like to check if it's a known problem.

The problem is reproducible with C2 only
