I would like to point out that the tyranids could destroy the dark eldar and the chaos gods, firstly the webway may be accessed through any number of largely unknown portals across the galaxy and also through the necron dolmen gates, this would allow the tyranids to enter and destroy the dark city of the eldar.

as for the chaos gods, entering the warp would not be neccessary, if all sentient life in the galaxy was killed then the chaos gods would be starved of the phsycic and emotional energy they provide and would dissipate, this would return the warp to the calm state it existed in before the war in heaven, perfect for the old ones to re-establish their empire.

also the tyranids would not have to destroy the necrons as many of them were destroyed during the great sleep and therefore without the c'tan to help them (as in the current edition of the story the necrons betrayed, fragmented and imprisoned the c'tan robbing them of the vast majority of their power) any returning old ones would easly wipe out remianing necron tomb worlds.
