* navigator.bluetooth is optional -- it may be manatory by the
  WebBluetooth spec, but the Rust code should still be able to handle
  the errors resulting from a browser not implementing the spec at all
  without panicking.

* requestDevice: While it's marked optional upstream, practically it's
  mandatory (the default value, an empty dictionary, is not accepted).

Contributes-To: #2381

We emit a shim function that sets the stack pointer,
so we can avoid emitting mutable globals.
Mutable globals aren't supported everywhere Wasm is.

We explicitly match on `Expr` in a few locations so it's necessary to
peel back `Expr::Group` like we do with `Type::Group`.

Closes #2393

Added some documentation to the `js_name` page about using it to import
JavaScript modules that use `export default`.
