Subject: Utilize the visibility map in autovacuum, too. There was an oversight
 in the visibility map patch that because autovacuum always sets
 VacuumStmt->freeze_min_age, visibility map was never used for autovacuum,
 only for manually launched vacuums. This patch introduces a new scan_all
 field to VacuumStmt, indicating explicitly whether the visibility map should
 be used, or the whole relation should be scanned, to advance relfrozenxid.
 Anti-wraparound vacuums still need to scan all pages.
