[Mesa-dev] [PATCH 5/9] i965: Move nir_lower_locals_to_regs a bit later.

From: Kenneth Graunke <kenneth at whitecape.org>

I'm going to add a boolean scheduling pass that I want run late, but
after copy propagation and dead code elimination.  Yet, I don't want
to have to think about registers.  So, move the register conversion
a little later.

No impact on shader-db.  Suggested by Jason Ekstrand.
