radv: use nir_opt_copy_prop_vars and nir_opt_dead_write_vars
Totals from affected shaders: SGPRS: 2856 -> 2856 (0.00 %) VGPRS: 3236 -> 3248 (0.37 %) Spilled SGPRs: 0 -> 0 (0.00 %) Spilled VGPRs: 0 -> 0 (0.00 %) Private memory VGPRs: 0 -> 0 (0.00 %) Scratch size: 0 -> 0 (0.00 %) dwords per thread Code Size: 236560 -> 233548 (-1.27 %) bytes LDS: 0 -> 0 (0.00 %) blocks Max Waves: 277 -> 283 (2.17 %) Wait states: 0 -> 0 (0.00 %) Even in the cases were we have increased VGPR use it appears the NIR is improved significantly.
