Do a big refactor.
- Replace the decidable predicates on expressions and statements with
separate data types.
- Reorganise the Hoare logic semantics to remove unnecessary
definitions.
- Make liberal use of modules to group related definitions together.
- Unify the types for denotational and Hoare logic semantics.
- Make bits an abstraction of array types.
