[aarch64-port-dev ] [11u] RFR (S) 8214922: Aarch64: Add vectorization support for fmin/fmax

[Dmitry Chuyko]

Hello,

Original RFE: https://bugs.openjdk.java.net/browse/JDK-8214922

Original patch applies almost cleanly except 2 added lines in 
src/hotspot/share/opto/vectornode.cpp because of missing part of context 
(JDK-8214751 not ported), they are added manually.

11u webrev: http://cr.openjdk.java.net/~dchuyko/8214922/webrev.11u.00/

Testing: tier1, tier2, TestFpMinMaxIntrinsics.

Thanks,
