Likely subtags minimization of und should be en.

[dminor]

According to test262, the likely subtags minimize operation applied to und should result in en.

To work on this bug:

• Code is found in:

  icu4x/components/locale_canonicalizer/src/locale_canonicalizer.rs

  Line 491 in b56441c

  pub fn minimize<T: AsMut<LanguageIdentifier>>(&self, mut langid: T) -> CanonicalizationResult {

• Unit tests are present here: https://github.com/unicode-org/icu4x/blob/main/components/locale_canonicalizer/tests/fixtures/minimize.json
• The algorithm is defined here: https://www.unicode.org/reports/tr35/#Likely_Subtags

Hi, thanks for offering to help! I'm not sure I can give much guidance beyond what I wrote down above. I think there's an algorithmic error in our implementation, so I'd suggest adding a failing test case, and comparing what is happening in our code to the description in https://www.unicode.org/reports/tr35/#Likely_Subtags.
