Fix in t_vp_build: Missed necessary updates sometimes
_mesa_update_state doesn't always reset VertexProgram._Current to NULL. This caused us to skip a necessary update of the fixed function vertex program sometimes. Change the logic such that we check for updates whenever the _Current program is either NULL or the program generated by t_vp_build.
