I'm an apologist of proportionality of measures. Start with simpler, less formal measures, and carry on from there. If need be, be more assertive as each measure fails.
Talk to him, but not in front of other studentsa whole class. For example, it can in a relatively empty hall of a building of a campus, or as he is leaving a class room. There must be people, if possible, but not too many. Don't isolate yourself when meeting him, and don't reprimand him in front of a crowd. This will increase the chances of attaining your goal, without much mess like some formal procedure. Go to you teacher and tell him what you're feeling when he makes those jokes about you. Tell him that you're being serious and you would like him to stop.
If he doesn't comply, and continues to behave in the same manner, then just proceed as it's described in some other answer to this question.
Without trying to the simpler measures first, and going head first with a timeline and a 'diary' of your interactions with him, you may come as somewhat 'neurotic', specially if they find out you're on the spectrum, and completely disregard your complaint.
