Port bugfix for incorrect heap deallocation on conditional operator (#627)

Browse Source 
* Revert 4f8917ec (experimental bugfix for heap in conditional)

* Port bugfix for incorrect heap deallocation on conditional operator (ported from compuphase upstream)

* Fix the upstream bugfix

Fixed the wrong order of heaplist nodes and the incorrect calculation of the max. heap usage.

* Add an additional pass for functions that return array if they are used before definition (inside definition (recursion) is a "before definition" situation too)
