        Description

        While investigating JDK-8194659, I've noticed that disabling UseSubwordForMaxVector (which is enabled by default) improves performance.

        The optimization reduces performance of the SPECjvm2008-MPEG benchmark by up to 3.5% and also affects performance of other benchmarks (see JDK-8194659 for details).
