Use cpyBetweenPhases as the copier for TreeTransformers

odersky · odersky · commit fdf17d050470 · 2017-10-22T13:16:16.000+02:00
TreeTransform used cpyBetweenPhases, but TreeTransformer did not.
This does not seem sensical. Most likely this was overlooked. TreeTransform/TreeTransformer
is too similar, one gets confused easily what is what.
