[SYCL][PI][OpenCL] The case of PI_DEVICE_INFO_ATOMIC_64

[zjin-lcf]

Does the case need to include double-precision floating-point check (FP64) in the OpenCL plugin interface ?

case PI_DEVICE_INFO_ATOMIC_64: {
   size_t extSize;
   cl_bool result = clGetDeviceInfo(
       cast<cl_device_id>(device), CL_DEVICE_EXTENSIONS, 0, nullptr, &extSize);
   std::string extStr(extSize, '\0');
   result = clGetDeviceInfo(cast<cl_device_id>(device), CL_DEVICE_EXTENSIONS,
                            extSize, &extStr.front(), nullptr);
   if (extStr.find("cl_khr_int64_base_atomics") == std::string::npos ||
       extStr.find("cl_khr_int64_extended_atomics") == std::string::npos)
     result = false;
   else
     result = true;
   std::memcpy(paramValue, &result, sizeof(cl_bool));
   return PI_SUCCESS;
 }
