[RFC 1/2] rust: Introduce atomic API helpers

[Boqun Feng <boqun.feng@gmail.com>]

In order to support LKMM atomics in Rust, add rust_helper_* for atomic
APIs. These helpers ensure the implementation of LKMM atomics in Rust is
the same as in C. This could save the maintenance burden of having two
similar atomic implementations in asm.
