Bug 1644878 - Don't define Map/Set identical iterator methods in self-hosted JS. r=arai
I think we were defining those methods in self-hosted JS, because that automatically gives
us the property that they all have the same identity. This causes bad error messages.
Instead redefine them in the finishInit ClassSpec hook. We still have the "wrong" methods
in the 'methods' array so that JSXray tests continue to pass.

Vendoring Puppeteer
===================
As mentioned in the chapter on [Testing], we run the full [Puppeteer
test suite] on try. These tests are vendored in central under
_remote/test/puppeteer/_ and we have a script to pull in the most
recent changes.
To update the vendored copy of Puppeteer under _remote/test/puppeteer/_:
% ./mach remote vendor-puppeteer
[Testing]: ./Testing.html
[Puppeteer test suite]: https://github.com/GoogleChrome/puppeteer/tree/master/test
