        JDK-8183103 was fixed by making PostLoopMultiversioning flag off by default and experimental. It was enough for workaround the problem until it is fixed JDK-8183390.

        But we have also concern about AVX3 stability because of insufficient testing on new Intel's hardware. We switched AVX3 off by default and made it experimental too.

        After discussions we agreed that making -XX:UseAVX=3 experimental was mistake. We should restore it to product value again.
