Hi all,

This is the v8 of LKMM atomics in Rust, you can find the previous

Changes since v7:

- A lot of trait renaming per the suggestion of Benno.
- Add new internal type `AtomicRepr<T>` to make Atomc*Ops function safe.
- Rename atomic/ops.rs => atomic/internal.rs per the suggestion of
  Benno.
- Move `Atomic<T>`, `AtomicType` and `AtomicAdd` into atomic.rs.
- Remove atomic/generic.rs and move `impl AtomciType for {i,u}{32, 64,
  size}` blocks and the tests into a new atomic/predefine.rs file.
- Make `internal` not public, except that `AtomicImpl` is public.
- Other minor documentation improvememt.

Regards,
Boqun
