; TypeSize error in the loop vectorization legality analysis. It is possible for
; a scalable/vector load to appear inside a loop at vectorization legality
; analysis if, for example, the ACLE are used. If we encounter a scalable/vector
; load, it should not be considered for analysis, and we should not see a
; TypeSize error.
