Well, you did write something about removing _EXPR nodes and
just using _STMT nodes in your reply to Tom.  I guess you
meant that the process of generating the lower-level format
would remove _EXPR nodes and just use _STMT nodes, not that
we would do so in tree.def.

If this lower-level representation is implemented using
tree nodes, then I still think it would be better to use
COND_EXPR instead of IF_STMT, just because I think the latter
is an abomination.  There is no reason why an intermediate
format couldn't just with the restriction that COND_EXPR has
void sub-expressions.
