Pull Request resolved: #13226 ## Context Previously, I updated the implementation of `aten.cat.default` in D76305343 (#11508) since the original implementation had a bug. The new implementation only supported up to 3 input tensors, but several models require the need for up to 6 input tensors. This diff updates the capabilities of the `concat` op so that any arbitrary number of input tensors may be accepted. ## Changes * Update implementation of the concat shader to be able to be called repeatedly, allowing support for any number of input tensors.
