Theoretically, according to the previous generation of science, there would be absolutely no genetic changes. Now, some are not so sure. The field of epigenetics is becoming murky, with some science showing there is gene transfer in situations like this. No idea about which genes, but it likely would be nothing dangerous.

Regarding the solanine question, potato tubers normally grow attached to plants with quite a bit of solanine, so grafting to a tomato likely is not much different. The main impact would probably be in yield of tomatoes or potatoes. Grafting like this likely reduces the potential harvest of both, since it divides the plant's energy into two areas, though even that is possibly not true.
