Fixed a bunch of errors in equal_computation

Errors are obvious, first of all the data of the constants don't have to scalars, and secondly, is not enough for outputs that have no owner to have same type, but they should have the same index (i.e. correspond to the same input). As I have all corresponding pairs of inputs in `common` and these outputs are equal with their inputs, is sufficient to check if them ( as pair) are part of common
