QueryGenerator.iter populates self.normalized with normalised titles data from the API, but this isnt used anywhere in the repo. It could be used by subclasses outside of the repo, and it probably _should_ be used by our own subclasses.
APISite.getredirtarget() performs its own info property query, and uses the same normalized data. It would probably be inefficient to convert this to using QueryGenerator
APISite.preloadpages already uses QueryGenerator, but uses self.sametitle instead of QueryGenerator.normalized to detect normalised titles.
