This serie implements the migration of some type into the new PDB reader. During the migration phase (this serie and next one), the types (A) will: - always be loaded by old PDB reader, - be migrated accoring to the type's tag (UDT, pointer, enum...), one commit for each tag by: + storing in new PDB reader an offset to that type inside the PDB file, + requesting type details directly from the file.
(A) typedef:s are handled differently than the other types, so they'll be taken care of later on.
