[vector] Additional tests for ternary ops to bring the coverage up

[Viswanathan, Sandhya]

Please find below a webrev which adds additional tests for Vector API ternary ops to bring the coverage up:
http://cr.openjdk.java.net/~sviswanathan/vectorIntrinsics/TestCoverage/part2/webrev.00/

Also, the scripts have been modified to generate only smoke tests for named methods
where the equivalent lanewise method tests exists.

Best Regards,
