Hi,
When reading code of Dependences::calculateDependences, I noticed that WAR is computed specifically by
buildWAR.  Given ISL now supports "kills" in approximate dataflow analysis, this patch takes advantage of it.
Though I don't know if it's intended not using the ISL "kills" functionality.

This patch also cleans up a couple lines redundant codes.  Any comments?

Thanks,
