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
