NIR is happy to take care of constant folding for us, and it's easier to do in SSA. This required adjusting of lower_precision unit tests to have un-folded constants. freedreno results look like noise. Some excerpts: total instructions in shared programs: 2718343 -> 2718412 (<.01%) instructions in affected programs: 6847 -> 6916 (1.01%) total last-baryf in shared programs: 109992 -> 110015 (0.02%) last-baryf in affected programs: 117 -> 140 (19.66%) total sstall in shared programs: 198312 -> 198297 (<.01%) sstall in affected programs: 148 -> 133 (-10.14%) total systall in shared programs: 432163 -> 432150 (<.01%) systall in affected programs: 1016 -> 1003 (-1.28%) Reviewed-by: Alyssa Rosenzweig <alyssa.rosenzweig@collabora.com> Reviewed-by: Timothy Arceri <tarceri@itsqueeze.com> Reviewed-by: Marek Olšák <marek.olsak@amd.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/21751>
