This moves some ops down to when they're needed, generally reducing the number of temps in use. It's not always a win -- sometimes you can end up moving a generator of a component used by a nir_op_vec down, which means that op's sources stay live while the vec (whose register likely gets coalesced with the ops creating it) is also live. But it's generally good. softpipe results: temps in affected programs: 18115 -> 18026 (-0.49%) imm in affected programs: 19 -> 22 (15.79%) r300 results: instructions in affected programs: 174 -> 178 (2.30%) vinst in affected programs: 156 -> 160 (2.56%) sinst in affected programs: 54 -> 50 (-7.41%) temps in affected programs: 2634 -> 2169 (-17.65%) Reviewed-by: Marek Olšák <marek.olsak@amd.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/14096>
