Dear all,

Would you please review this simple change?
Bug: https://bugs.openjdk.java.net/browse/JDK-8211908
Webrev: http://cr.openjdk.java.net/~mhorie/8211908/webrev.00

Since PPC64 supports SLP with VSX, we can have the benefit from enabled SuperWordLoopUnrollAnalysis on PPC64.

In the attached micro benchmarks, performance improved by 1.7x at maximum. In SPECjvm2008, the score improved by a couple of % in xml.validation and scimark.lu.large

(See attached file: microbench_slp.tar.gz)

Best regards,
