Renumber some unit tests

[Bruno Haible]

Recently I've been annoyed by the numbering of locale-dependent unit tests:
  - some test the C locale first,
  - some test the C locale last,
  - some don't test it at all.

For consistency, I'm renumbering them such that
  - the C locale comes first ('1'),
  - then comes one or more locales with MB_CUR_MAX == 1,
  - then comes UTF-8,
  - then some legacy multibyte encodings,
  - finally GB18030.

This makes it easier to find the code for specific encodings in the tests.
