- is recognized by the boolean selector.

- We differ two flavors of this Cond. The first, the dense Cond, passes
- control along output i if the selector value is i, 0 <= i <= n. If the
- selector value is >n it passes control along output n.
- The second Cond flavor differences in the treatment of cases not specified in
- the source program. It magically knows about the existence of Proj nodes.
- It only passes control along output i, 0 <= i <= n, if a node Proj(Cond, i)
- exists. Else it passes control along output n (even if this Proj does not
- exist.) This Cond we call "fragmentary". There is a special constructor
- new_defaultProj that automatically sets the flavor.
