gallivm: kill old per-quad face selection code

Not used since ages, and it wouldn't work at all with explicit derivatives now
(not that it did before as it ignored them but now the code would just use
the derivs pre-projected which would be quite random numbers).

v2: also get rid of 3 helper functions no longer used.
