aco: only require texture coordinates to be in WQM if NSA is used
From comment in emit_mimg(): We don't need the bias, sample index, compare value or offset to be computed in WQM but if the p_create_vector copies the coordinates, then it needs to be in WQM. fossil-db (GFX10.3): Totals from 1778 (1.28% of 139391) affected shaders: SGPRs: 105080 -> 105072 (-0.01%); split: -0.02%, +0.01% VGPRs: 96800 -> 96776 (-0.02%); split: -0.07%, +0.05% CodeSize: 10001120 -> 10001384 (+0.00%); split: -0.04%, +0.04% MaxWaves: 18164 -> 18163 (-0.01%) Instrs: 1883750 -> 1883598 (-0.01%); split: -0.06%, +0.05% Cycles: 34800176 -> 34767840 (-0.09%); split: -0.10%, +0.01% We don't have a p_create_vector if we use NSA.
