Prevents shader-db regression, since NIR puts just everything to x and the pair scheduling is not smart enough to fix it later, espetially after presubtract happens. Together with the previous patches that move the shadow lovering to NIR this results in the following shader-db stats: RV530: total instructions in shared programs: 129598 -> 128697 (-0.70%) instructions in affected programs: 19001 -> 18100 (-4.74%) helped: 124 HURT: 9 total presub in shared programs: 8554 -> 8314 (-2.81%) presub in affected programs: 1099 -> 859 (-21.84%) helped: 17 HURT: 50 total temps in shared programs: 17514 -> 17000 (-2.93%) temps in affected programs: 1368 -> 854 (-37.57%) helped: 45 HURT: 18 total cycles in shared programs: 191286 -> 190593 (-0.36%) cycles in affected programs: 32369 -> 31676 (-2.14%) helped: 110 HURT: 29 RV410: total instructions in shared programs: 112805 -> 112618 (-0.17%) instructions in affected programs: 7089 -> 6902 (-2.64%) helped: 65 HURT: 21 total presub in shared programs: 3244 -> 3314 (2.16%) presub in affected programs: 228 -> 298 (30.70%) helped: 7 HURT: 47 total temps in shared programs: 18163 -> 18138 (-0.14%) temps in affected programs: 710 -> 685 (-3.52%) helped: 36 HURT: 19 total cycles in shared programs: 169530 -> 169369 (-0.09%) cycles in affected programs: 11304 -> 11143 (-1.42%) helped: 63 HURT: 27 The stats are a bit less awesome for Rv410, since it can't run the heavy Unigine Tropics shaders where this helps the most due to the TEX indirection limits.
