      Description

      The load acquire implementation in orderAccess_aix_ppc.hpp still contains a workaround from the time in which we were using xlC 10.1:
      We use lwsync instead of twi+isync which is used on linux.
      This compiler is no longer supported and the VM has been tested with xlClang++ 16.1 (JDK13) without the workaround.
      (Already JDK8-12 require at least xlC 12.01. Also see https://wiki.openjdk.java.net/display/Build/Supported+Build+Platforms)
