    (ffi/calling-conventions)

    Get an array of all supported calling conventions on the current 
    architecture. Some architectures may have some FFI functionality 
    (ffi/malloc, ffi/free, ffi/read, ffi/write, etc.) but not support 
    any calling conventions. This function can be used to get all 
    supported calling conventions that can be used on this 
    architecture. All architectures support the :none calling 
    convention which is a placeholder that cannot be used at runtime.
