Summary: OpenCL 2.0 specification defines '-cl-uniform-work-group-size' option, which requires that the global work-size be a multiple of the work-group size specified to clEnqueueNDRangeKernel and allows optimizations that are made possible by this restriction. The patch introduces the support of this option. To keep information about whether an OpenCL kernel has uniform work group size or not, clang generates 'uniform-work-group-size' function attribute for every kernel: - "uniform-work-group-size"="true" for OpenCL 1.2 and lower, - "uniform-work-group-size"="true" for OpenCL 2.0 and higher if '-cl-uniform-work-group-size' option was specified, - "uniform-work-group-size"="false" for OpenCL 2.0 and higher if no '-cl-uniform-work-group-size' options was specified. If the function is not an OpenCL kernel, 'uniform-work-group-size' attribute isn't generated.
