If the machine only uses 8 Byte vectors, we get an exception in the static initializer because the code tries to use a 4 Byte vector which is unsupported (stack trace: see JBS issue [JDK-8369511](https://bugs.openjdk.org/browse/JDK-8369511)). This is an alternative to https://github.com/openjdk/jdk/pull/27749.
