[8u] RFR for backport of JDK-8188868: PPC64: Support AES intrinsics on Big Endian

[Kazunori Ogata]

Hi,

May I get reviews for enhancement backport of JDK-8188868: PPC64: Support 
AES intrinsics on Big Endian?

http://cr.openjdk.java.net/~horii/jdk8u_aes_be/8188868/webrev.00/

There is no code change except for an immediate parameter of vsldoi (-8 in 
jdk8u was changed to 8 to match with the latest code), besides the 
difference of directory tree structure.

Since not a small number of customers are still using jdk8, especially in 
AIX, JDK-8188868 is important for them to improve performance of secure 
network transportation.


Regards,
Ogata
