I think in the lectures he mentioned how it was useful for optimising
indirect calls - usually we have to assume an indirect call could call any
other function - I think control flow analysis helps you to narrow down
which functions it could call. This gives you a simpler call graph, which is
good because... err... I'm not sure... someone finish my answer please!
