move liveness interface to its own header

Currently, the interface for liveness analysis is declared in the flow.h header file. There is no a real need to move it to its own file but it's the dual of the previous patch and help a bit to make the code structure clearer. Move the prototype for liveness analysis to its own header. Signed-off-by: Luc Van Oostenryck <[email protected]>
