compiler: refactoring in Export class to encapsulate type refs map

Convert the Export::type_refs map from a static object to a field
contained (indirectly, via an impl class) in Export itself, for better
encapsulation and to be able to reclaim its memory when exporting is
done. No change in compiler functionality.
