Runner dumps

The files below were generated by the Intel Graphics Compiler after setting the IGC_ShaderDumpEnable=1 variable. OCL_asmX_before_spirv_backend.spv is the input binary SPIR-V generated by the IGC's OpenCL frontend, from which the SPIRV-LLVM-Translator generates OCL_asmX_before_spirv_backend.ll module which is passed to the SPIR-V backend. The backend outputs OCL_asmX_after_spirv_backend.spv SPIR-V binary which returns to IGC to be translated to LLVM module OCL_asmX_after_spirv_backend.ll for further compilation.
