[Beignet] [PATCH 1/3] Add one script for generating the PCH files.

[junyan.he at inbox.com]

From: Junyan He <junyan.he at linux.intel.com>

The gen_ocl_pch will be used to generate the PCH files
based on the different CL options.
the -u file will be used to force update the PCH files,
ignore the Clang version
