Description
I'm currently going through the web-stable-diffusion demo, and I'm finding that the clip_to_text_embeddings function isn't adding functions to the exported IRModule, causing the assert to fail. This issue seems to have started appearing after March 20th, and I'm working to track down the isuse in the repo:
This seems to happen on MacOS and Linux. I haven't tried in Windows because PyTorch doesn't support compiled models on Windows yet.
I'm not sure if there's been an API change on TVM, or if this is a TVM bug or an issue with the demo.

Research direction
Start with the web-stable-diffusion demo and the clip_to_text_embeddings function on the latest tvm/unity branch. Compare the exported IRModule with the failing assertion and determine whether the cause is a TVM API change or a demo issue; done when the assertion passes on the reported MacOS and Linux setups.
