Add support for \aset in pgbench
This option is similar to \gset, except that it is able to store all
results from combined SQL queries into separate variables. If a query
returns multiple rows, the last result is stored and if a query returns
no rows, nothing is stored.
While on it, add a TAP test for \gset to check for a failure when a
query returns multiple rows.
