radeonsi/nir: make use of nir_lower_load_const_to_scalar()
This allows NIR to CSE more operations. LLVM does this also so the impact is limited, however doing this in NIR allows other opts to make progress. For example some loops in Civilization Beyond Earth shaders are unrolled. Reviewed-by: Marek Olšák <[email protected]>
