As far as I understand it, the massive comment updates are just a result of adding these functions, such that the assembly printing passes have more information available to them? In which case there's no way to split out the test changes from the implementation; it would be possible to add the hooks in separate commits so that the size of the individual commits are minimized, but I think that landing it all as one commit is better in this case: the main threat of changing so many files is if this commit has to be reverted after changes are placed on top of it, or if it similarly interferes with another revert; if that does happen though, splitting this into multiple commits would make the problem worse. Better to get it all done in one push imo, ymmv etc.
