nir: add pass to move load_const
Run this pass late (after opt loop) to move load_const instructions back
into the basic blocks which use the result, in cases where a load_const
is only consumed in a single block.
This helps reduce register usage in cases where the backend driver
cannot lower the load_const to a uniform.
