Comment (by tom):

 the flag for enabling wasm is on the JSContext

 ​https://searchfox.org/mozilla-
 central/rev/c0ca77697c6868482f30af873ec8069f2c080a34/js/public/ContextOptions.h#24

 We would need to push it down to CompartmentOptions. And then we can
 enable it per-Compartment, and enable it for Chrome but not Content.
