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.

@DingliZhang, @RealFYang: Can one of you please check if this is also fine for RISC-V, please?
