Last I checked, the spinning and non-spinning pile driver were in Haggar's moveset in Final Fight 1. I can't remember if to do it you had to grab the opponent, jump, and then press punch and jump at the same time, or if you had to do a full 360 degree motion. I think it was the latter. However, I distinctly remember him having it. You could use it to knock down swarms of badguys as everything in its path would get knocked down.
