Global link hints; revert b7535a604954b5873d825eb66bfecd08f1f2c99b.

Here's why:

- b7535a604954b5873d825eb66bfecd08f1f2c99b is complicated and complex (O(n^2)).
- With experience, it is not obviously better than what was there
  before, and in some cases it's worse.
- b7535a604954b5873d825eb66bfecd08f1f2c99b selects way too much text in
  some cases; e.g. on Google Inbox, it selects text lengths in the tens
  of thousands of characters.  That cannot be useful.
- With global hints, this extra cost (resulting from passing large
  objects between frames) is significant and noticable.
- The simpler approach of accounting for text length when scoring
  filtered hints (tweaked here: 5cbc5ad702a01a81b98f8c82edb3b6d227c2c7b5)
  works better in practice.
