Gleb Shchepa ccab4d8771 Bug #53034: Multiple-table DELETE statements not accepting ...

"Access compatibility" syntax

The "wild" "DELETE FROM table_name.* ... USING ..." syntax
for multi-table DELETE statements is documented but it was
lost in the fix for the bug 30234.

The table_ident_opt_wild parser rule has been added
to restore the lost syntax.


mysql-test/r/delete.result:
  Test case for bug #53034.
mysql-test/t/delete.test:
  Test case for bug #53034.

  Bug #53034: Multiple-table DELETE statements not accepting
              "Access compatibility" syntax
  
  The table_ident_opt_wild parser rule has been added
  to restore the lost syntax.
  Note: simple extending of table_ident with opt_wild in
  the table_alias_ref rule is not acceptable, because
  a) it adds one conflict more and b) this conflict resolves
  in the inappropriate way.
