Hm, we are calling get_vectype_for_scalar_type with a vector type argument
which has OImode (thus type_for_mode fails).
We can robustify get_vectype_for_scalar_type a bit, but maybe we should
fix the caller (BB vectorization) as well. Not sure though, it might
still vectorize v2si operations to v2di ones for example.
Mine.
