[Beignet] [PATCH 4/4] add utest for load spir binary.

Sun Mar 8 20:24:28 PDT 2015
From: Luo Xionghu <xionghu.luo at intel.com>
To generate SPIR binary, please refer to the page
https://github.com/KhronosGroup/SPIR.
For llvm3.2, the command is "clang -cc1 -emit-llvm-bc -triple
spir-unknown-unknown -cl-std=CL1.2 -include opencl_spir.h
compiler_ceil.cl -o compiler_ceil32.spir"
For llvm3.5, the option -cl-kernel-arg-info is required,
and option -fno-builtin is required to avoid warning.
v2: add missing load_program_from_spir.cpp file.
