freedreno/ir3: lower immeds to const
Helps reduce register pressure and instruction counts for immediates
that would otherwise require a mov into gpr.
total instructions in shared programs: 4455332 -> 4369297 (-1.93%)
total dwords in shared programs: 8807872 -> 8614432 (-2.20%)
total full registers used in shared programs: 263062 -> 250846 (-4.64%)
total half registers used in shader programs: 9845 -> 9845 (0.00%)
total const registers used in shared programs: 1029735 -> 1466993 (42.46%)
half full const instr dwords
