Structs are currently handled as pointer + byval, which makes AMDGPU LLVM backend generate incorrect code when structs are used. This patch changes struct argument to be handled directly and without flattening, which Clover (Mesa 3D Gallium OpenCL state tracker) will be able to handle. Flattening would expand the struct to individual elements and pass each as a separate argument, which Clover can not handle. Furthermore, such expansion does not fit the OpenCL programming model which requires to explicitely specify each argument index, size and memory location. Patch by Vedran Miletić llvm-svn: 279463
