[PATCH] D32060: BitVector: add iterators for bits that are set

[Zachary Turner via llvm-commits]

Instead of having the value type be an index, how about having it be a
range? Eg if bits,1,2,3,6,8,9 are set then have it return (1,4), (6,7), and
(8,10) on successive iterations. This should be much more efficient. For a
bits_unset iterator, the above would return (0,1), (4, 6), (7,8), (10,
size())
