ramil/ram@mysql.com/ramil.myoffice.izhnet.ru dc8d3d0bec Fix for bug #26447: "ALTER TABLE .. ORDER" does not work with InnoDB ...

and auto_increment keys

Problems: 
  1. ALTER TABLE ... ORDER BY... doesn't make sence if there's a 
     user-defined clustered index in the table.
  2. using a secondary index is slower than using a clustered one 
     for a table scan.

Fixes:
  1. raise a warning.
  2. use the clustered index.
