Fix for BUG#8023.
Allow LIMIT clause after DUAL.
mysql-test/r/limit.result:
Added test result for BUG#8023.
mysql-test/t/limit.test:
Added test for BUG#8023.
sql/sql_yacc.yy:
Allow the specification of a LIMIT clause after DUAL. This is needed for queries as:
select a from t1 union all select 1 from dual limit 1;
In this query LIMIT is applied to the whole UNION, so it makes sense, however, the
current parser did not allow any clause after DUAL.
