Alexander Barkov a433c65575 A cleanup for MCOL-4064 Make JOIN collation aware 
After creating and populating tables with CHAR(5) case insensitive columns,
in a set of consequent joins like:

select * from t1, t2 where t1.c1=t2.c1;
select * from t1, t2 where t1.c1=t2.c2;
select * from t1, t2 where t1.c2=t2.c1;
select * from t1, t2 where t1.c2=t2.c2;

only the first join worked reliably case insensitively.

Removing the remaining pieces of the code that used order_swap() to compare
short CHAR columns, and using Charset::strnncollsp() instead.
This fixes the issue.
