Summary:
This is the second of 3 stack diffs to deal with replacing the parser of types.
This diff is about changes to translate record types, as well as class types and enum
types. For class types and enum types we store the declaration pointer in the map of
types to find the type easier later.
For record declarations, we change the way we build record names.
Moreover, we don't translate typedefs anymore, because when we have a pointer to a typedef,
we can find the actual type it points to.
