While the checks are considered useful, the attribute does dangerous optimizations, removing NULL checks where they can be needed. Remove the uses of this attribute introduced in r281130: the changes were inspired on Google's bionic where this attribute is not used anymore. In general, the __nonnull() attribute has fulfilled its roll and will be replaced with the Clang _Nonnull qualifier in the future. END
