I think all of those have software implementations ("VMs")†, although it's true that some of them have hardware implementations as well ("native instruction sets"). Since the IBM 360, though, the distinction has been very fuzzy.
† although Intel Gen, RADEON, and the NVIDIA GPU ones might be an exception
