Revert ill-considered change of index-size fudge factor. This partially reverts commit 21a39de5809cd3050a37d2554323cc1d0cbeed9d, restoring the pre-9.2 cost estimates for index usage. That change introduced much too large a bias against larger indexes, as per reports from Jeff Janes and others. The whole thing needs a rewrite, which I've done in HEAD, but the safest thing to do in 9.2 is just to undo this multiplier change.
