[vector] RFR(T/S) 8242889: test/jdk/jdk/incubator/vector/VectorConversionTests.java fails by timeout

[Paul Sandoz]

Hi,

Thanks for doing this.  If you are gonna separate you could you place common code in a base class?

I believe everything but vector species constants and the @Test annotated methods could be shared.

Thanks.
Paul.
