Generify reference indices to prepare for generic instances

Browse Source 
We use indices into the TypesByReferenceIndex table to defer type lookup
during model construction. However, this won't support fully generic
instances (which might not be in the type table at all). This patch
introduces a new TypeRef abstraction which can either represent a fixed
index or an instantiated generic type.
