-; Check that DAGCombiner correctly folds the following pairs of shuffles
-; using the following rules:
-;  1. shuffle(shuffle(x, y), undef) -> x
-;  2. shuffle(shuffle(x, y), undef) -> y
-;  3. shuffle(shuffle(x, y), undef) -> shuffle(x, undef)
-;  4. shuffle(shuffle(x, y), undef) -> shuffle(undef, y)
-;
-; Rules 3. and 4. are used only if the resulting shuffle mask is legal.
