It was removed because highly outdated by 3.1 changes. The asm code is
useless with Glide 3.x. I think it is a waste of time to update the asm
code when we will switch to the Glide 3.0 in a short time.

Vertex snapping is done inside the Glide 3.x when required (only Voodoo
1 and Voodoo Rush). Even with the old code was done only for the Voodoo
1/Rush.
I didn't notice any performance difference removing the asm code
(PentiumII+Voodoo2), however if the difference is noticeable with a
Voodoo 1, we can restore the asm code at last for vertex snapping.
