Report the names of unsupported operators in flatbuffer_loader.cpp (#73865)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/73865
- Report the names of unsupported operators in `flatbuffer_loader.cpp`:
```
TORCH_CHECK(
unsupported_op_names.empty(),
"Unsupported ops: ",
c10::Join(", ", unsupported_op_names));
```
- Use `TORCH_CHECK` instead of `AT_ASSERT` because `AT_ASSERT` is deprecated (see https://www.internalfb.com/code/fbsource/[9fbf30fa6401f8b341c3100c90f9d929a8ad7f9b]/fbcode/caffe2/c10/util/Exception.h?lines=585)
