Allow ctuples as return type of optimised builtins and use it for
divmod()of C integers.Also make sure that we prefer function signatures with wider numeric types over those with narrower types if there are multiple alternatives. This helps when calling functions with mixed integer types (e.g. arguments
int, longshould call a function withlong, longrather thanint, int).Supersedes and closes #6520
