Evgeny Potemkin 60fc8507bd Bug#30302: Tables that were optimized away are printed in the 
EXPLAIN EXTENDED warning.

Query optimizer searches for the constant tables and optimizes them away. This
means that fields of such tables are substituted for their values and on later
phases they are treated as constants. After this constant tables are removed
from the query execution plan. Nevertheless constant tables were shown in 
the EXPLAIN EXTENDED warning thus producing query that might be not an
equivalent of the original query.
        
Now the print_join function skips all tables that were optimized away from
printing to the EXPLAIN EXTENDED warning. If all tables were optimized away it
produces the 'FROM dual' clause.

  Bug#30302: Tables that were optimized away are printed in the
  EXPLAIN EXTENDED warning.
  Now the print_join function skips all tables that were optimized away from
  printing to the EXPLAIN EXTENDED warning. If all tables were optimized away it
  produces the 'FROM dual' clause.
sql/table.h:
  Adjusted test case result after fix for the bug#30302.
  The optimized_away flag is added to the TABLE_LIST struct.
