; Verify that shuffles are canonicalized according to rules:
; shuffle(B, shuffle(A, Undef)) -> shuffle(shuffle(A, Undef), B)

; (shuffle(shuffle A, Undef, M0), A, M1) -> (shuffle A, Undef, M2)
;
; As a result, all the shuffle pairs in each function below should be
; combined into a single legal shuffle operation.
