Some instructions from the original loop, when vectorized, can become trivially dead. This happens because of the way we structure the new loop. For example, we create new induction variables and induction variable "steps" in the new loop. Thus, when we go to vectorize the original induction variable update, it may no longer be needed due to the instructions we've already created. This patch prevents us from creating these redundant instructions. This reduces code size before simplification and allows greater flexibility in code generation since we have fewer unnecessary instruction uses.
