Description: Avoid emitting __proto__ in generated output
Replace {__proto__: null, ...} with Object.setPrototypeOf({...}, null)
in generated code. The __proto__ property in object literals does not
work when Node.js runs with --disable-proto, which is used in Debian
autopkgtests. Object.setPrototypeOf is a proper API that works in all
environments and preserves getter semantics for live bindings.
