May I get review for backport of 8158232: PPC64: improve byte, int and 
long array copy stubs by using VSX instructions?

This changeset looks no conflict with the latest jdk8u-dev code, but the 
patch command failed to apply it.  It seems the patch command lost the 
code regions to apply patches because stubGenerator_ppc.cpp has sets of 
similar (but slightly different) functions.

I created new webrev mainly to update line numbers in the patch file.  I 
verified I can build fastdebug and release builds and there was no 
degradation in "make test" results.
