canonical(CanonicalizerTool tool,

Similar to
Canonicalizable.canonical(CanonicalizerTool), except that
implementations should act as if the current input of the node was the given one, i.e.,
they should never look at the inputs via the this pointer. |

invertStamp(Stamp outStamp)
Computes the stamp of the input for the given output stamp.
