Message:

No, silly runtime, AST nodes are not for you.

Reviewed by Sam Weinig.

We still use AST nodes (ScopeNodes, particularly FunctionBodyNodes) within
the runtime, which means that these nodes must be persisted outside of the
arena, contain both parser & runtime data, etc. This is all a bit of a mess.

Move functionality into a new FunctionExecutable class.
