There are a couple changes in this PR that help getting clang-repl to run in the browser. Using a jupyterlite instance for the example pasted below 1) Updating flags responsible for generating shared wasm binaries that need to be dynamically loaded Most Importantly as can be seen in the changes `shared` and `allow-undefined` are crucial.  2) While exiting we encounter this.  Now as can be seen herecd418030de/clang/lib/Interpreter/Interpreter.cpp (L421-L430)We call cleanUP in the destructor. Now cleanUP through IncrementalExecutor tries to deinitialize the JIT which wasn't even intialized as runCtors in wasm.cpp is a no-opcd418030de/clang/lib/Interpreter/IncrementalExecutor.cpp (L94-L101)cd418030de/clang/lib/Interpreter/Wasm.cpp (L107-L109)
