This change was partially scripted and partially done manually with vim regex + manually placing the deleted constructors. The script change looked for destructors in the public: section of a class, if that existed the deleted constructors would go before the destructor. For manual placement I looked for any constructor in the public: section of the corresponding class. If there wasn't one, then it would ideally have gone as the first entry except below enums, classes and typedefs. This may not have been perfect, but is hopefully good enough. Fingers crossed. #include "base/macros.h" is removed from files that don't use ignore_result, which is the only other thing defined in base/macros.h.
