WebAssembly and Exception Handling (throw)

Hey all,

After getting clang-repl running in the browser, I worked on integration it with jupyterlite. Xeus-cpp, a C++ Jupyter kernel provides a way to integrate it. Here is a static link that can be used to try C++ completely in the browser (https://compiler-research.org/xeus-cpp/lab/index.html) . An example notebook `xeus-cpp-lite-demo.ipynb` has been provided to show what all can be acheived.

Coming back to the issue. I see we can't run `throw` (or a try catch blocking involving throw) while running clang-repl in the browser.


The debug logs tell me that this comes from dlopen


All this can be tried through the static link above.
