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. The __nonnull() attribute will be deprecrated from our headers and replaced with the Clang _Nonnull qualifier in the future. MFC after: 3 days
