052aa466e1 Further optimize worklist management 
Instead of always popping the first elements, do multiple complete
iterations of the worklist until it is empty.

d7e7f74b24 Factor out common binary op code in range inference

compound assignment variants, factor the range computation out
into a separate function.

* PHP-7.1:
  Updated reference-counting inferece rules. The previous rules refected PHP-5 behavior and were completely wrong for PHP-7. (e.g. scalars don't have reference counters at all). This change shouldn't affect anything, because results of this inference are not used yet.
