Function mz_transform::literal_constraints::undo_preparation

fn undo_preparation(
    mfp: &mut MapFilterProject,
    orig_mfp: &MapFilterProject,
    relation: &mut MirRelationExpr
) -> Result<(), RecursionLimitError>

The above preparation might make the MFP more complicated, so we’ll later want to either undo the preparation transformations or get back to orig_mfp.
