Fix for bug#50946: fast index creation still seems to copy the table
Problem: ALTER TABLE ADD INDEX may lead to table copying if there's
numeric field(s) with non-default display width modificator specified.
Fix: compare numeric field's storage lenghts when we decide whether
they can be considered 'equal' for table alteration purposes.
