There doesn't seem to be much benefit in always providing declarations for the sized deallocations from C++14 onwards if the user explicitly passed `-fno-sized-deallocation` to disable them. This patch simplifies the declarations to be available exactly when the compiler expects sized deallocation functions to be available.
