A recent patch has added custom legalization of vector conversions of `v2i16` -> `v2f64`. This just rounds it out for other types where the input vector has an illegal (narrower) type than the result vector. Specifically, this will handle the following conversions:

  v2i8 -> v2f64
  v2i32 -> v2f64
  v4i8 -> v4f32
  v4i16 -> v4f32
