Add some #[inline(always)] to arithmetic methods of integers I tried to add it only to methods which return results of intrinsics and don't have any branching. Branching could made performance of debug builds (`-Copt-level=0`) worse. Main goal of changes is allowing wider optimizations in `-Copt-level=1`.
