; The alignment of 16 causes type legalization to split this as 3 loads,
; v16f32, v4f32, and v4f32. This loads 24 elements, but the load is aligned
; to 16 bytes so this i safe. There was an issue with type legalization building
; the proper concat_vectors for this because the two v4f32s don't add up to
; v16f32 and require padding.
