Now, we should support almost all atomics(including loads and stores), besides atomic |

@FractalFir sorry, I had to force push while rebasing for some reason |
c_char depends on platform, so clippy will complain on linux when it passes on macOS

Should be good to go, once the CI finishes. |

Currently, Rust-CUDA only supports CUDA-specifc atomics, and does not support the atomic operations provided by the Rust standard library.
This PR aims to address that, and emulate those intrinsics(by using CUDA-specific ones). The fix I implement is described in: #253
Once this PR(with the basic infrastructure for intrinsics) gets merged, we can add support for all the other intrinsics, allowing a lot more Rust code to run on the GPU - out of the box.
