Request for approval: JDK-8130341 "GHASH 32bit intrinsics has AEADBadTagException"

[Yuri Gaevsky]

Hello,

Please approve backport of JDK-8130341 "GHASH 32bit intrinsics has AEADBadTagException"
to jdk8u which is a required follow-up fix for the issue mentioned in [1].

Bug:
  https://bugs.openjdk.java.net/browse/JDK-8130341

JDK9 review thread:
  http://mail.openjdk.java.net/pipermail/hotspot-compiler-dev/2015-July/018402.html
JDK9 changeset:
  http://hg.openjdk.java.net/jdk9/jdk9/hotspot/rev/36fd5d1982b0

Webrev:
  http://cr.openjdk.java.net/~ygaevsky/8130341.8u/webrev.hotspot/
  NB: The original change for JDK9 does apply cleanly to jdk8u codebase w/
  minor correction to the test path (test/compiler/codegen/7184394/ -->
  test/compiler/7184394/).

Testing:
  windows-i586: (known failures mentioned in [1] are gone)
  windows-x64:
    JTREG tests: 
      (jdk8u) hotspot/test/compiler/7184394/
      (jdk8u) jdk/test/com/sun/crypto/provider/Cipher/AES/
    (also checked the output from TestAESMain for performance improvements w/
     -XX:+UseGHASHIntrinsics)
    
Thank you,
