What *should* happen is that FOR_INIT_STMT (in the case where it 
declares a new variable) would be a DECL, together with explicit 
information about how that DECL is (a) initialized -- such as a 
CALL_EXPR giving the constructor to call and the parameters to use -- 
and (b) finalized -- such as a CALL_EXPR giving the destructor to call.

Then, during lowering (a phase we don't have yet), we'd convert it into 
GENERIC.

To be clear, I'm not asking you to undo your change; we're not close 
enough to the ideal here to make it worthwhile.
