Initial Commit: Based on TI OpenCL v0.8, originally based on clover.shamrock_v0.8

This is a continuation of the clover OpenCL project:
        http://people.freedesktop.org/~steckdenis/clover

based on the contributions from Texas Instruments for Keystone II DSP device:
        git.ti.com/opencl

and adding contributions from Linaro for ARM CPU-only support.

See README.txt for more info, and build instructions.
