[Beignet] [PATCH] Generate most of the vector builtin functions automatically

[He Junyan]

Good python script and decrease the ocl_std header file size a lot.

1.There is a typo at backend/src/CMakeLists.txt,   set (ocl_blob_c_file 
${GBE_SOURCE_DIR}/src/ocl_stdlib_str.c) should be .cpp
2. ocl_vector.h seems to be generated every time in build but the 
ocl_as.h, ocl_convert.h  need to be updated using the
update script. I think we can unify the manner here.
3. about the pch file, I think I need to do some investigation in clang 
to find the exactly not compatible args. I think now you can
just use the pch when no buiding args passed, and once there are some 
extra buiding args, totally fallback to the old manner.
