[vector] failing tests

[Brian Goetz]

I have done a clean checkout of the vectorIntrinsics branch, and I'm 
finding that the test for jdk.incubator.vector are not all passing:

TEST FAILURE

The failures seem to have been introduced before

The intervening commits look like they were all related to AMD support, 
one of these is the culprit:
