Stack from ghstack:
Previously the profiler would think Tensors would require grad, even
when the no_grad flag is enabled during execution. This makes the profiling
and guards respect the no_grad flag, which eliminates extra differentiable
graphs that appear in the backward graph (where no_grad is typically enabled).
