most optimization and inferences were implemented for the vanilla ways (as ints, lists ..etc) of defining control values, those were ported to ProductOfSums, but for SumOfProduct they didn't make sense in most cases, however in this case what you do in the constructor effectivelly transforms SumOfProducts to ProductOfSums representation, looks good to me |

Simplify the
SumOfProductscontrol value when possible (if there's only a single product in it) when constructing aControlledGate. This allows theX.controlled() -> CXoptimization when using aSumOfProductscontrol value.Add a two-step test to check
X.controlled(num_qubits=2) -> CCXoptimization, and include SumOfProducts check there too.Make use of this simplification where we were hacking it in previously.
Fixes #5883
