// Make sure that we can compile CUDA files that include <future> and use
// std::shared_future.
//
// At one point in time this didn't work because clang defined different values
// for __GCC_ATOMIC_INT_LOCK_FREE on host and device.  This caused libstdc++
// not to define std::shared_future when compiling for device, resulting in
// compile errors (even though we only use std::shared_future in host code).
