Fix bug #14016 date_format() 2nd parameter was compared using case insensitive
collation
By default constant strings in second parameter of date_time() have case
insensitive collation. Because of this expressions date_format(f,'%m') and
date_format(f,'%M') wrongly becomes equal, which results in choosing wrong
column to sort by.
Now if second parameter of date_format() is constant then it's collation is
changed to case sensitive.
