We can add code to remove the empty CONSTRUCTOR in the C++ front-end. 
But it's only useful when all initializers are non-constrant and split 
out. When there are constant initializers, they will be left in the 
CONSTRUCTOR and result an non-empty CONSTRUCTOR. The gimplifier handles 
with such CONSTRUCTOR and removes it if it becomes empty. So we don't 
need to duplicate the code to remove the empty CONSTRUCTOR in the C++ 
front-end.
