Thanks @TheRealMDoerr .  I didn't even consider atomic bitwise operations, but that's a good idea.  I'm not in a hurry to push this, so if you could provide an atomic bitwise patch for ppc64, I would be happy to include it.  In the mean time, I'm still investigating the ZGC regression.  If I can figure it out, I might want to include a fix for ZGC in this PR as well.
