Missing Tidy Bot comments?

[Adar Lieber-Dembo]

I just fixed an issue that prevented some patches from receiving Tidy
Bot comments. If you have a non-trivial patch and you were wondering
why clang-tidy wasn't giving you any recommendations, it's likely
because of this. If you rebase your patch on top of master and push a
new revision, clang-tidy will work again.
