Detailed Description

A concrete lowering ("implementation") of an AtomicScalarOpNode.

An AtomicScalarOpImpl bundles two pieces of knowledge that used to be spread across AtomicScalarOpNode (verify_impl_exits_*) and the dispatchers:

which (data type, atomic op) combinations it actually supports, and
how to generate code for a node using this implementation.

Each concrete implementation is a stateless singleton, obtained via its instance() method, and is tied to exactly one ImplementationType. This keeps a node's implementation_type in sync with the impl used to reason about and lower it.
