pan/bi: Emit load_vary ops
...
Annoyingly long code to do so, but this should theoretically work for
both direct and indirect load_vary. Still need to handle destination.

At the moment, we just iterate the clauses in the post-RA, post-sched IR

In preparation for a Panfrost-based non-Gallium driver (maybe
