lima/ppir: more tex rework and optimization

No regressions in deqp and piglit.

I'm aware patch "lima/ppir: improve handling for successors in other blocks" is a little hacky as explained in the commit message. I appreciate suggestions on how to solve that in a better way if there is one now. I plan on keep working on the scheduler after this so I think that's when we may be able to have a proper solution (and possibly put successors in other blocks to succ_list and not break anything).
