Because we're seeing very very little value in having the control
structures -- in fact they make just about everything we do in terms
of CFG manipulations more difficult than it needs to be.
In fact, the only value I see in having the control structures is that
it can make DCE faster and they make it somewhat easier to parse the
dump files.
