Summary: Pull Request resolved: https://github.com/facebook/yoga/pull/1677 We have Clang Tidy warnings enabled internally, that will flag `const YG*Ref` as misleading, as a const pointer to non-const, instead of non-const pointer to const. Let's remove all the misleading const in existing tests, and generated tests. Reviewed By: joevilches Differential Revision: D59335968 fbshipit-source-id: c66af878904ba7900f8ffcd99162968d90f8e5c7
