This is needed to implement optimizations that remove a node that produced
a tuple. The node can be replaced by the Tuple operation so that the
following Proj nodes have not to be changed. (They are hard to find due to
the implementation with pointers in only one direction.) The Tuple node is
smaller than any other node, so that a node can be changed into a Tuple by
just changing its opcode and giving it a new in array."""
