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).
