brw_postprocess_nir contains a lot of stuff these days. The first part
does a bunch of lowering and cleanup optimizations in SSA form. The
second part does some post-optimization lowering and the out-of-SSA
conversion.
We may want to do additional work before the post-optimization/post-SSA
phase. Splitting this allows us to insert such tasks in the "middle".
For convenience, brw_postprocess_nir() becomes a wrapper which invokes
both parts, so callers can continue working as they did until they have
a reason to do otherwise.
