      For details on the java.lang.Thread.onSpinWait() methods refer to the parent task.

      This subtask adds a new method onSpinWait() to java.lang.Thread class with a legitimate implementation that is empty. A corresponding x86 hotspot intrinsic allows to actually benefit from this spin loop hint by injecting a 'pause' instruction into the c2 compiled code.
