Support parenthesized syntax for CLUSTER without a table name.

Browse Source 
b5913f6120 added a parenthesized syntax for CLUSTER, but it
requires specifying a table name.  This is unlike commands such as
VACUUM and ANALYZE, which do not require specifying a table in the
parenthesized syntax.  This change resolves this inconsistency.
This is preparatory work for a follow-up commit that will move the
unparenthesized syntax to the "Compatibility" section of the
CLUSTER documentation.
