History
Benjamin Kramer 37bc2f3216 [Reassociate] Similar to "X + -X" -> "0", added code to handle "X + ~X" -> "-1". 
Handle "X + ~X" -> "-1" in the function Value *Reassociate::OptimizeAdd(Instruction *I, SmallVectorImpl<ValueEntry> &Ops);
This patch implements:
TODO: We could handle "X + ~X" -> "-1" if we wanted, since "-X = ~X+1".

Patch by Rahul Jain!
