I know this is terminology already in clang-doc, but lets come up w/ something a bit more informative than "Reducing Infos". TBH, the whole "Infos" bit has always rubbed me the wrong way, so even just `Reducing Results` is better IMO.  Use your judgement, but I think we can find a better name for these than `Infos`.
