bar@mysql.com/bar.myoffice.izhnet.ru 4eebfd09c2 Bug#28875 Conversion between ASCII and LATIN1 charsets does not function ...

(Regression, caused by a patch for the bug 22646).
Problem: when result type of date_format() was changed from
binary string to character string, mixing date_format()
with a ascii column in CONCAT() stopped to work.
Fix:
- adding "repertoire" flag into DTCollation class,
to mark items which can return only pure ASCII strings.
- allow character set conversion from pure ASCII to other character sets.
