Hello!
I'm currently engaged in the delightful work of milling the floor in the basement. Old paint+carpet glue, and some type of asphalt (?) in another room, need to be removed. Built in 1960, walls of lightweight concrete, not drained but no signs of moisture, located on a glacial ridge.
The floor becomes moderately rough after sanding.
Should I use primer before tiling? Does it prevent potential moisture migration? Will the tiles come loose otherwise, or is it enough with watery adhesive?

You should definitely use primer; it is an adhesion primer that helps the make fix stick. Most primers are diffusion-open, so they allow any moisture to pass through.
Read the respective primer's can; it usually states what properties it has.
GOOD LUCK!

I have the following primer at home; http://www.mapei.it/Referenze/Multimedia/532_sv.pdf
I can't quite determine whether it has a vapor retarding effect or not...
Can someone help me interpret this?

it works excellently! you should definitely prime.
it says in the pdf file: "not intended to block rising moisture from the substrate" and you don't want that!
