Add an heuristic directive.

@param[in] backend the target backend @param[in] atom the target atom @param[in] type the type of the heuristic modification @param[in] bias the heuristic bias @param[in] priority the heuristic priority @param[in] condition the condition under which to apply the heuristic modification @param[in] size the number of atoms in the condition @return whether the call was successful; might set one of the following error codes:
