    Description

      VectorMask.laneIsSet was modified in https://bugs.openjdk.org/browse/JDK-8273949, which intends to use VectorMask.toLong to get performance gain. That works when the platform supports toLong well, but degrades the performance once it's not.

      VectorMask.laneIsSet is heavily used in test cases, checking mask value for other mask operations.
