Hi,

please review small patch for 8202395: AARCH64: wrong encoding for SIMD 
instructions zip, trn, uzp

encoding for zip2, trn1, trn2, uzp1, uzp2 instructions was hardcoded as 
zip1 instruction(so, initially created opcode parameter wasn't used). 
This patch fix it.


CR: https://bugs.openjdk.java.net/browse/JDK-8202395

webrev: http://cr.openjdk.java.net/~dpochepk/8202395/webrev.01/

testing: I've tested this patch with intrinsic(which found this bug) 
with zip2 instruction usage


Thanks,

Dmitrij
