Summary: This fixes type indices for SDK or CRT static archives. Previously we'd try to look next to the archive object file path, which would not exist on the local machine. Also error out if we can't resolve a type server record. Hypothetically we can recover from this error by discarding debug info for this object, but that is not yet implemented.
