Original RFE: https://bugs.openjdk.java.net/browse/JDK-8239386

Original patch applied with fuzz, so the hunk was manually put in the 
right place (after prefetch distance masking).

11u webrev: http://cr.openjdk.java.net/~dchuyko/8239386/webrev.11u.00/

Testing: tier1, tier2 (aarch64). Default ContendedPaddingWidth is still 
128 on HW with smaller cache line.
