-/// PointerIntPair - This class implements a pair of a pointer and small
-/// integer.  It is designed to represent this in the space required by one
-/// pointer by bitmangling the integer into the low part of the pointer.  This
-/// can only be done for small integers: typically up to 3 bits, but it depends
-/// on the number of bits available according to PointerLikeTypeTraits for the
-/// type.
-///
-/// Note that PointerIntPair always puts the IntVal part in the highest bits
-/// possible.  For example, PointerIntPair<void*, 1, bool> will put the bit for
-/// the bool into bit #2, not bit #0, which allows the low two bits to be used
-/// for something else.  For example, this allows:
-///   PointerIntPair<PointerIntPair<void*, 1, bool>, 1, bool>
-/// ... and the two bools will land in different bits.
