[cfe-commits] [PATCH] Support for universal character names in identifiers

[Jordan Rose]

  Many more tests.

  This is actually now four patches in my git repo, which is how I'm planning to commit it:

  - Unify diagnostics for \x, \u, and \U without any following hex digits.
  - Handle universal character names and Unicode characters outside of literals.
  - As an extension, treat Unicode whitespace characters as whitespace.
  - Add a fixit for \U1234 -> \u1234.
