David Farler	3b9f1bd77f	FlaggedPointer should only compose with itself ... <rdar://problem/19104060> LLVM's PointerIntPair always picks the highest bits of the available low order free bits but NumLowBitsAvailable is the number of *lowest* bits available from the LSB. This could cause problems with overwriting when putting a FlaggedPointer inside a PointerIntPair. Just don't allow it. Add a static assert to make sure there are enough bits to support the number of nested FlaggedPointers. Add a helper constexpr min function which isn't available until C++14.
