// The VisitedLinkDatabase contains the following fields:
// `id` - the unique int64 ID assigned to this row.
// `link_url_id` - the unique URLID assigned to the row where this link url is
//               stored in the URLDatabase. ID is stored to avoid storing the
//               URL twice.
// `top_level_url` - the GURL of the top-level frame where the link url was
//                 visited from.
// `frame_url` - the GURL of the frame where the link was visited from.
// `visit_count` - the number of entries in the VisitDatabase corresponding to
//               this row (must exactly match the <link_url, top_level_url,
//               frame_url> partition key).
