Don't allow VACUUM VERBOSE ANALYZE VERBOSE.

There are plans to extend the syntax for ANALYZE, so we need to break
the link between VacuumStmt and AnalyzeStmt.  But apart from that, the
syntax above is undocumented and, if discovered by users, might give
the impression that the VERBOSE option for VACUUM differs from the
verbose option from ANALYZE, which it does not.
