The LLVM backend does this when lowering ordered_xfb_counter_add_amd. I
guess there is some missing dependency checking or something.

These are intended to make sure that the post-RA optimizer works
correctly across control flow. The new tests emit a divergent
if-else branch (with full logical+linear CFG).
- dpp_across_cf:
Simple case of DPP optimizable across control flow. Should pass.
- dpp_across_cf_overwritten:
Similar case but the DPP source register is overwritten in CF.
This shows a bug so the test fails now (will be fixed).

This commit adds the skeleton of a new ACO post-RA optimizer,
which is intended to be a simple pass called after RA, and
is meant to do code changes which can only be done
after RA.
It is currently empty, the actual optimizations will be added
in their own commits. It only has a DCE pass, which deletes
some dead code generated by the spiller.

With NGG, ngg_gs_known_vtxcnt[0] would be false and ngg_gs_finale() would
assert.
With legacy GS, I don't know why the assertion was there.
