-/* Used to hold all the components required to do SSA PHI elimination.
- The node and pred/succ list is a simple linear list of nodes and
- edges represented as pairs of nodes.
-
- The predecessor and successor list: Nodes are entered in pairs, where
- [0] ->PRED, [1]->SUCC. All the even indexes in the array represent
- predecessors, all the odd elements are successors.
-
- Rationale:
- When implemented as bitmaps, very large programs SSA->Normal times were
- being dominated by clearing the interference graph.
-
- Typically this list of edges is extremely small since it only includes
- PHI results and uses from a single edge which have not coalesced with
- each other. This means that no virtual PHI nodes are included, and
- empirical evidence suggests that the number of edges rarely exceed
- 3, and in a bootstrap of GCC, the maximum size encountered was 7.
- This also limits the number of possible nodes that are involved to
- rarely more than 6, and in the bootstrap of gcc, the maximum number
- of nodes encountered was 12. */
