Alexey Bataev 27daa0afed [SLP]Fix PR39774: Set ReductionRoot if the original instruction is vectorized. ... Summary: If the original reduction root instruction was vectorized, it might be removed from the tree. It means that the insertion point may become invalidated and the whole vectorization of the reduction leads to the incorrect output result. The ReductionRoot instruction must be marked as externally used so it could not be removed. Otherwise it might cause inconsistency with the cost model and we may end up with too optimistic optimization.
