        Description

        ShenandoahAlwaysPreTouch flag dates back to the times when ShenandoahHeap used VirtualSpace for reserving/committing heap. To workaround single-threaded pretouch code in VirtualSpace, a new flag was needed:
         https://mail.openjdk.java.net/pipermail/shenandoah-dev/2016-October/000892.html

        That code is long gone now, and current Shenandoah just reserves/commits from OS directly. Therefore, this flag is no longer needed. It actually confuses logging in JDK-8245720.
