libstdc++-v3/ChangeLog:
* testsuite/22_locale/codecvt/codecvt_unicode.cc: Rename
functions.
* testsuite/22_locale/codecvt/codecvt_unicode.h: Make more
generic so it accepts char8_t.
* testsuite/22_locale/codecvt/codecvt_unicode_wchar_t.cc: Rename
functions.
* testsuite/22_locale/codecvt/codecvt_unicode_char8_t.cc: New test.
