-/* We distinguish three kinds of Cond nodes. These can be distinguished
- by the mode of the selector operand and an internal flag of type cond_kind.
- First we distinguish binary Conds and switch Conds.
- A binary Cond has as selector a boolean value. Proj(0) projects the control
- flow for case "False", Proj(1) the control flow for "True". A binary Cond
- is recognized by the boolean selector.
- The switch Cond has as selector an unsigned integer. It produces as result
- an n+1 Tuple (cf0, ... , cfn) of control flows.
- 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.
- The two switch flavors are distinguished by a flag of type cond_kind.
- Default flavor is "dense"
