Use childNodes helper + Add source locations for some translation failures

Just manual testing so far - do you have any thoughts on what our testing strategy should be?

Welcome!

My plan for testing was to construct TranslateC and CheckFile build steps from input test case files similar to how it is currently done in the Zig repo. That of course depends on a TranslateC build step which I started working on in https://github.com/ziglang/translate-c/tree/build-step but so far I've mostly been re familiarizing myself with the various parts of the build system.

Once that system works I plan on copying over all the current cases and adding something like // expect=fail to the non-passing cases to make it easy to track progress.

Hello, I have been lurking at ziglang organisation and noticed this new repo. First of all, thank you both (and squeek502 and TwoClocks and all other Aro contributors) for your work on that compiler, it is very cool project and I often enjoy reading new issues and code there :)

I guess this repo was not announced yet?

There's not much to announce yet but the intention of this repo is to implement ziglang/zig#20630
