I don't think the order of evaluation is defined (we should consult  
the standard).  If there is an explicit control-flow dependency  
between the subexpressions, we should put that explicitly in the CFG.   
In that case visiting the subexpressions from right-to-left or left-to- 
right won't matter (as the expressions will have already been  
evaluated).
