31 Calc_output_layout method is called only when output layout is invalidated.
32 It means, that it is called when:
33 1) It has never been called.
34 2) Dependency has changed output layout.
35 In this both cases, we need to recalc branch_true and branch_false.
36 !* We can be sure, that this method was called AT LEAST once during graph compilation.*!
