Ian Romanick 38a94c82e6 intel/fs: Don't optimize out 1.0*x and -1.0*x ... This (sort of) matches the behavior of nir_opt_algebraic. This ensures that subnormal values are properly flushed to zero. With the aid of "nir/search: Float sources of texture instructions are float users" and "nir/search: Transitively apply is_only_used_as_float", there would have been no shader-db regressions on Intel platforms. However, those caused a significant increase in compile time. Since the instruction regressions were so small, I just dropped those commits rather than improve them. All Haswell and newer platforms had similar results.
