This change seems to be causing problems on the emscripten auto-roller:  https://ci.chromium.org/ui/p/emscripten-releases/builders/try/linux/b8780394114149321217/overview

Failures show up in ubsan tests and look like this:

  error: symbol '_Z4testi' unsupported subtraction expression used in relocation in code section.
  error: symbol '__main_argc_argv' unsupported subtraction expression used in relocation in code section.
  fatal error: error in backend: function sections must contain one function each

It seems like enabling this sanitizer perhaps uses features we don't yet support?  I will keep investigating but perhaps we can find a way to revert he effect on the wasm backend for now?
