The NIR path through the frontend is effectively the only one maintained for a quite a while now. We can see that effect with !15540, where the TGSI generation path was regressed to assertion fail on real-world shaders, and nobody noticed until I came along trying to test the NIR-to-TGSI transition. We already have a nir_to_tgsi() call for translating NIR representation for ARB programs into TGSI before handing them off to the driver. This change makes that path get taken for GLSL programs as well. This is the minimum change to get all the drivers on NIR from GLSL, to give a simple commit to bisect too. The dead code removal comes next. Now every driver benefits from shared NIR optimizations for GLSL, and we can start retiring GLSL optimizations.
