…s gather/scatter (llvm#3829) In torch.index_put like ops, `values` is only required to be broadcastable to `input[indices]`, rather than exact dimension match. This patch fixes the problem by add additional stablehlo.dynamic_broadcast_in_dim before creating stablehlo.scatter op. BTW, this patch also enhance the `getBroadcastResultShape` utility in hlo namespace.
For the op `index_put_`, if accumulate == false, the behavior is undefined if the indicies aren't unique (https://pytorch.org/docs/stable/generated/torch.Tensor.index_put_.html). So, when converting `AtenIndexPutHackedTwinOp` to a TMTensor scatter op, mark the indices as unique if when `accumulate == false`. This should have no functional effect (unless users are relying on UB) and assuming unique indices has the benefit of unlocking better optimizations in further compiler stages.
