[WebAssembly] Is there a way to enable standard exception handling in clang?

[sunfishcode]

Is there a way to enable standard (non-legacy) exception handling instructions for C++ exceptions in clang?

I know about --wasm-use-legacy-eh=false in llc, however I'm looking for in a way to do this from the clang command line.

-mllvm -wasm-use-legacy-eh=false doesn't work?

Ah, I forgot about -mllvm. Thanks!
