      Description

      The following JCK tests show errors when running with -Xcomp -XX:-TieredCompilation since JDK-8256823 was integrated:
      api/java_lang/Integer/rotateLeft:
      Failed for :(80000000,1), result: 40000000 vs c0000000
      api/java_lang/Integer/rotateRight:
      Failed for :(80000000,1), result: 1 vs ffffffff
      api/java_lang/Long/rotateLeft:
      Failed for :(8000000000000000,1), result: 4000000000000000 vs c000000000000000
      api/java_lang/Long/rotateRight
      Failed for :(8000000000000000,1), result: 1 vs ffffffffffffffff
      Seems like the rotateLeft issues are only reproducible with debug builds on some machines.
