clang-p2996/llvm/test/Transforms/IndVarSimplify
History
Max Kazantsev d6dd938589 [IndVars] IV user should not prevent use widening 
Sometimes the an instruction we are trying to widen is used by the IV
(which means the instruction is the IV increment). Currently this may
prevent its widening. We should ignore such user because it will be
dead once the transform is done anyways.
