Fix and re-enable post loop vectorization

    Details

      Description

      The fix for JDK-8183103 disabled PostLoopMultiversioning and AVX=3 in JDK 9 by default due to problems with the vectorization of post loops.

      We should implement a full fix and re-enable both features in JDK 10 (or a JDK 9 update release).
