Summary: This diff is part of a bigger effort to remove the RTTI flags. To do so we need to remove occurrences of `dynamic_cast` and other functions that rely on runtime type informations. Changelog: [Internal][Changed] - Removed extra asserts relying on dynamic_cast Reviewed By: JoshuaGross Differential Revision: D30483554 fbshipit-source-id: 92b31281841a92c7b43e918938248431265dd654
