Update lint declaration example

[JohnTitor]

Fixes #712

[tshepang]

huh, such much speeds 😮

[JohnTitor]

We now use declare_lint_pass macro instead of defining manually. Should we do manually for clarify?

[JohnTitor]

Hm, the link error is unrelated to this, I'll submit another PR not to block the process.

So, r? @nikomatsakis or @Mark-Simulacrum as per git blame

Seems fine to me though without the context as to what upstream changes caused this I can't be sure the new code is good. Someone from clippy can likely give better guidance than I.

But r=me on the changes presuming they compile.

[JohnTitor]

I think the issue here is that while_true lint example is entirely outdated and now on EarlyLintPass.

@Mark-Simulacrum It'd be great if you could approve this so that "Review required" is satisfied :)

[JohnTitor]

cc @rust-lang/wg-rustc-dev-guide it'd be great if someone could also review here :)

It's been a long time since I looked at this code, and it keeps changing a bit over time.

I'm personally fine with merging this and fixing later, if you think that would be the best path forward.

Oh sorry, missed the notification. Feel free to ping me on Zulip in the future, that's much more likely to get through.

[JohnTitor]

Thanks both!
