mesa: split _mesa_reference_program() into hot/cold paths.
inline the hotpath of the reference remaining the same. This shouldn't
penalise the slow path at all but improve the hot path so we don't have
to jump to the function.
It also moves some assert checks under an #ifndef NDEBUG.
Minor clean-ups added by Brian.
