Semantic information is held by `sem::Node`s which describe the program at
a higher / more abstract level than the AST. This includes information such as
the resolved type of each expression, the resolved overload of an intrinsic
function call, and the module scoped variables used by each function.

Semantic information is generated by the `Resolver` when the `Program`
is built from a `ProgramBuilder`.
The `semantic::Info` class holds a map of `ast::Node`s to `semantic::Node`s.
The `sem::Info` class holds a map of `ast::Node`s to `sem::Node`s.
This map is **many-to-one** - i.e. while a AST node might have a single
corresponding semantic node, the reverse may not be true. For example:
many `ast::IdentifierExpression` nodes may map to a single `semantic::Variable`,
and so the `semantic::Variable` does not have a single corresponding
many `ast::IdentifierExpression` nodes may map to a single `sem::Variable`,
and so the `sem::Variable` does not have a single corresponding
`ast::Node`.
Unlike `ast::Node`s, semantic nodes may not necessarily form a directed acyclic
