 *  The common fields are:
 *
 *  - firm_kind - A firm_kind tag containing k_type.  This is useful
 *                for dynamically checking whether a node is a ir_node.
 *  - arity     - The number of predecessors in the Firm graph.
 *  - in        - A list with the predecessors in the Firm graph.  There are
 *                routines to access individual elements and to obtain the
 *                array.  The method returning the array should not be used.
 *  - mode      - The mode of the node.  There are routines to get the mode
 *                but also to access the mode's fields directly.
 *  - opcode    - The opcode of the node. There are routines to get the opcode
 *                but also to access the opcode's fields directly.
 *  - node_nr   - A unique number for the node.  Available only if debugging
 *                is turned on.

/* 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.
344
   We differ two flavors of this Cond.  The first, the dense Cond, passes
345
346
   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.
347
   The second Cond flavor differences in the treatment of cases not specified in
348
349
350
351
352
   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.
353
354
   The two switch flavors are distinguished by a flag of type cond_kind.
   Default flavor is "dense"
