Without looking it up, probably signalling distress to other humans and triggering a nurturing effect in those who see it to increase herd survival rate. Possibly could also work to mildly cleanse toxins and irritants from the eyes.

all the sadness collects in the mucus membranes of your eyes, so the tears are there to flush the sad away

Different tears have different chemical makeups as well, which I always thought was interesting. Tears brought on by emotion have more of a certain protein than tears brought on by a reflex. Why that is? I could not tell you without researching.

It's probably got something to do with emotional complexity of humans and needing to vent certain stuff off certain ways to keep going and not crack. Also, as was said, to signal distress to other people. We're a herd species.

I heard once that the smell of tears acts as a sexual turn off and can help prevent sexual assaults, though I don't know how that actually serves an evolutionary benefit

I could see that being beneficial for the purposes of choosing a more suitable mate than the assaulty fellow.

Just like tearing up is to help clear physical particles in the eye, emotional tears are supposed to help clear emotional hurdles.

I hear if you pull a hair from your anus it can make your eyes water so maybe that's a reason.

That's just the way it worked out. There's no special reason behind it, just like how opening your mouth wide and exhaling softly but audibly signals "bed time, pass it on". We know it's a signal, that much is clear, but as to why a given reflexive behavior became biologically linked to a given social signal is anybody's guess.

It's a sociologically-motivated adaptation of the original function of tears (clearing one's eyes), but how exactly it came about I'm not sure; if I had to take shots in the dark I would say that it's either something we evolved to add to our distress signals to parents when we're children, and/or it evolved to provoke others to show mercy, as humans do seem prone to killing each other a lot.

Yawning has a biological reason. It intakes oxygen quickly in order to cool the brain. Your brain naturally heats up the longer you stay awake.
