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). This is an alternative to https://github.com/openjdk/jdk/pull/27749.

@TheRealMDoerr I think I prefer this solution 😊 

Though I wonder if we need to add some kind of label for the `jtreg` changes? I'm not familiar with the code there.
But I can surely approve the test changes :)
