[PATCH 0/1] MR226: vkd3d-shader/hlsl: Fold redudant casts again after lower narrowing casts.

[Francisco Casas (＠fcasas)]

lower_narrowing_casts() currently creates a new cast calling
hlsl_new_cast(). This cast may be redudant, but it is not folded, which
is making SM1 emit an unnecessary fixme in some shaders:

    Aborting due to not yet implemented feature: SM1 "cast" expression.

Other passes that call hlsl_new_cast() are lower_int_division() and
lower_int_modulus(), so the new fold_redudant_casts() pass is called
after these as well.

This is the only thing left required for the HLSL compiler to properly compile the SONIC CD shaders.
