Previously if you wanted to match the statement associated with
a case or default block, you had to use hasDescendant.  Review
comments stated that hasDescendant is heavy-handed and that a
more specific narrowing matcher was preferred.  This is that
narrowing matcher.

- Separate matcher definitions with a blank line.
- Add corresponding unit tests for new narrowing matcher.
- Add the new matcher to the Registry
- Add documentation in the AST matchers reference HTML page.
- Remove trailing semi-colon from REGISTER_MATCHER macro to be consistent with the other macro declarations and fix a missing semi-colon in the invocation of the macro.
