[PATCH] D22279: [ADT] Add FlagsEnum, used to enable bitwise operations on enums without static_cast.

Oh, I understand why we have to use ADL to pick up these operator overloads.  As written, if anyone declares any overload of, say, `operator|`, in the global namespace, then our overloads won't be found.

I will change this again.  Maybe finally it'll be right...
