I understand previously we weren't storing any metadata for the bit vector,
but I think this addition could be a little clearer by at least commenting that
these indexes are based on the order of the calls in getMetadataBuilder(). It
would probably be worth it to add a comment up on the method itself that these
additions are order sensitive.
