This change was made by add_new_check.py and looking at the code, it's been
confused by the `readability::`. I'll move it to the right place and add a
`using readability::NamespaceCommentCheck` so we can drop the `readability::`
and have add_new_check.py get it right in future.

None that are likely to occur. `getName()` with some way to check that there's
no enclosing namespace would be equivalent. Is there a cheap way to tell if a
namespace is at the top level?

+Currently this works by finding all variables of unsigned integer type whose
+initialize begins with an implicit cast from ``Register`` to ``unsigned``.

It was meant to be 'initializer'. I'll correct that

Added tests for the following cases that do not make changes*
1. Similar interface but not called Register
2. Register class not inside llvm namespace
3. Calling a function that takes an llvm::Register with a llvm::Register
argument
4. Calling a function that takes an unsigned and is given an llvm::Register
argument
5. Initializing an llvm::Register using an llvm::Register argument
6. Initializing any other object using a constructor parameter that's unsigned
and a llvm::Register argument
7. Assigning to a member of llvm::Register
8. Assigning to a unsigned member of any other object
*4, 6, and 8 should eventually but don't yet
