Patrick Rudolph bisected the radeonsi regression to:
2f4705afde707e8eb41b9414c25df91aa1ea2fb3

Checking the attached TGSI, it seems the lighting constants were not declared
properly (which is illegal), and in conjunction with the behaviour introduced
by this commit (which is legal), it caused the shader to never stop.

The bug was thus a nine bug. Patch sent to the mailing list:
