Provides rustc related crates that not in crates.io

[liigo]

Docs of HIR, MIR, etc. are useful for some developers.

@liigo we have links to the standard library and a few other resource under the 'Rust' dropdown in the navigation panel. If you have any specific links you would like, feel free to open a new issue (or make a PR adding them yourself, mentoring instructions here: #137 (comment))

[liigo]

@jyn514 there's no rustc related api docs listed in the 'Rust' dropdown currently, so i don't think this issue is resolved.

[jyn514]

Ah sorry I misread rustc as rust.

[jyn514]

Mentoring instructions:

• In templates/navigation.hbs, add links to https://doc.rust-lang.org/stable/rustc/ and any other links you find helpful.

[liigo]

Thank you!

[jyn514]

Also, @pietroalbini are you comfortable adding links to rustc specifically? I know it's currently the only Rust implementation, but mrustc is a thing and I'm not sure if others are planned (in the far future) ...

[emilyalbini]

The link I think @liigo mentions is https://doc.rust-lang.org/nightly/nightly-rustc/rustc/.

I don't think adding the link itself is worth though: it's only needed for people working on the compiler, and it's shown on the home page of the contributor guide.

[jyn514]

Maybe it would be helpful to link to the contributor guide instead?

[emilyalbini]

Hmm, I still don't see much value in that, as a rustc contributor should already know that.
