We see two compiler/rtm/locking tests failing regularly on ppc64le in JDK11.

1. The test compiler/rtm/locking/TestRTMSpinLoopCount.java fails like this:
java.lang.RuntimeException: Total aborts count (1002) should be less or equal to 1001: expected that 1002 <= 1001

2. The test compiler/rtm/locking/TestRTMAbortThreshold.java fails like this:
