Dear all,

I would like to request reviews for this s390-only enhancement:
Bug:    https://bugs.openjdk.java.net/browse/JDK-8180823
Webrev: http://cr.openjdk.java.net/~lucy/webrevs/8180823.00/

The code for AES intrinsics in stubGenerator_s390.cpp is reworked to get rid of multiple copies of basically the same code snippets. Some chances for minor performance improvements are also taken advantage of.

The code has been active locally @SAP for several weeks now. No problems popped up.

Thank you!
