Track related symbols in resolver

As well as the already-implemented tracking of the existing definition
of redefinitions, the resolver will now also track the definition that
resolves each reference, and the references resolved by each definition.
Instead of using tuples to hold this information, named wrapper structs
have been created for each category.
