Gather nodes are vectorized as simply vector of the scalars instead of relying on the actual node. It leads to the fact that in some cases we may miss incorrect transformation (non-matching set of scalars is just ended as a gather node instead of possible vector/gather node). Better to rely on the actual nodes, it allows to improve stability and better detect missed cases. Differential Revision: https://reviews.llvm.org/D135174
