Added support for SEA IR.

- Modified makefile to take the existance of SEA_IR_ART
  file to mean "switch to sea ir mode".
- Switching SEA IR mode on leads to the new compiler being
  fed the fibonacci methods only, if they are used as input.
- Added partial support for the control flow subgraph of
  the SEA IR (instruction nodes and region nodes for
  conditional and unconditional branches).
