65876d3f - Change aten::native_layer_norm signature to match torch.layer_norm definition (#48971)

Change aten::native_layer_norm signature to match torch.layer_norm definition (#48971) Summary: This PR is to change the `aten::native_layer_norm` and `aten::native_layer_norm_backward` signature to match `torch.layer_norm` definition. The current definition doesn't provide enough information to the PyTorch JIT to fuse layer_norm during training. `native_layer_norm(X, gamma, beta, M, N, eps)` => `native_layer_norm(input, normalized_shape, weight, bias, eps)` `native_layer_norm_backward(dY, X, mean, rstd, gamma, M, N, grad_input_mask)` => `native_layer_norm_backward(dY, input, normalized_shape, mean, rstd, weight, bias, grad_input_mask)` Pull Request resolved: https://github.com/pytorch/pytorch/pull/48971 Reviewed By: izdeby Differential Revision: D25574070 Pulled By: ngimel fbshipit-source-id: 23e2804295a95bda3f1ca6b41a1e4c5a3d4d31b4
