[Beignet] [PATCH v8 2/2] test builtin function "shuffle"

[Zhigang Gong]

Homer,

All the patches before this email have been pushed to the master
branch right now.

As there is a big change in the ocl_stdlib.h due to python autogen
scripts and pch patches (merge all header files into one), you have
to manually merge the following v9/v10/... patches into current
master branch. Rebase your local branch will not help here.

The header file is move to ocl_stdlib.tmpl.h. Any question, please feel
free to contact me directly.
