[8u-dev] RFR for non-clean backport of 8154156: PPC64: improve array copy stubs by using vector instructions

[Doerr, Martin]

Hi Ogata,

I haven't seen any manual adaptations. You only had to pick parts of different changes if I didn't miss anything. I think the selection makes sense.
Looks good to me.

I think it will be helpful to get an incremental webrev if you do such changes again in the future. That would make it much easier to see what you've done.

Best regards,
Martin

Hi,

May I get review for non-clean backport of 8154156: PPC64: improve array 
copy stubs by using vector instructions?

This is the same change as I posted in January [1], but I updated the 
patch based on the latest jdk8u-dev tree.  As we've had ppc-expert 
reviewers in jdk8u-dev community, I'd like to request for review.

Original patch: http://hg.openjdk.java.net/jdk/jdk/rev/c9d756fa846e
Weberv: http://cr.openjdk.java.net/~horii/jdk8u_aes_be/8154156/webrev.02/

I confirmed it was buildable for both release and fastdebug builds, and 
JTREG caused no degradation.
