Although not especially easy to see, on my May 2015 Model S, "LAMISAFE" is imprinted on both parts of the panoramic roof glass and the liftgate. So I have answered my own question.
This means Tesla's glass prevents the glass roof explosions in other automobile brands that have recently been the subject of articles in Consumer Reports and other media. Lamisafe has also been certified by The Skin Cancer Foundation, a U.S. medical nonprofit, as filtering out 99% of UV radiation.
It would be interesting to hear whether all Tesla models in all years have laminated glass in all-glass roofs and sunroof/ panoramic roofs. I suspect laminated glass is used across the board, but would like confirmation.
