Having less shader instructions is a good thing, although clamps
tend to be pretty cheap. But to me it seems a little shaky to
justify this based only on the fact that some d3d8 application
might regress. It would perhaps be a different story if e.g. this
was always set in practice on common hardware.
Radeon cards set the flag and clamp, Nvidia cards don't clamp and
don't set the flag.
I did some git archeology, and it turns out the clamp was deliberately
added by patch 2d810bdc892fc028d4180066c46649709058267f. Matteo, do
you remember if this fixed a particular game?

Another factoid is that Microsoft's WARP renderer seems to clamp in
d3d8, but not d3d9. That's another indication that there is some d3d8
game that depends on it.
