…nal views to avoid copying) Pull Request resolved: #11509 These were reverted due to internal test failures. Sending this as an exported internal diff so that we can make sure we get internal signal. Original summary for #11294 (to make the GLU test input asymmetric): This way it will produce different results along each tested dim. Original summaryfor #11295: GLU requires slicing the input Tensor into two halves. Currently, we accomplish this by copying; ExecuTorch does not support views in general because it requires Tensors to be contiguous. However, nothing stops us from implementing [the ATen that uses views](https://github.com/pytorch/pytorch/blob/main/aten/src/ATen/native/GatedLinearUnit.cpp#L35) entirely internally to the op. To support this, I added `support_noncontiguous_tensors` as an optional template argument to BroadcastIndexesRange and plumbed it through to the elementwise_util functions as an optional SupportNonContiguousTensors parameter. ghstack-source-id: 289432903 Differential Revision: [D76311585](https://our.internmc.facebook.com/intern/diff/D76311585/)
