Philipp Schaad 2f3073b5cb [Polly][GPGPU] Added SPIR Code Generation and Corresponding Runtime Support for Intel ... Summary: Added SPIR Code Generation to the PPCG Code Generator. This can be invoked using the polly-gpu-arch flag value 'spir32' or 'spir64' for 32 and 64 bit code respectively. In addition to that, runtime support has been added to execute said SPIR code on Intel GPU's, where the system is equipped with Intel's open source driver Beignet (development version). This requires the cmake flag 'USE_INTEL_OCL' to be turned on, and the polly-gpu-runtime flag value to be 'libopencl'. The transformation of LLVM IR to SPIR is currently quite a hack, consisting in part of regex string transformations. Has been tested (working) with Polybench 3.2 on an Intel i7-5500U (integrated graphics chip).
