Its great when clang-format is the ubiquitous tool for all formatting regardless of the language. clang-formats existing integration into common editors/IDEs means we can build on the clang-format legacy to help contribute in a small way to the future of Carbon, simply by helping providing native Carbon support.

Following the excellent talk by @chandlerc et al at CppNorth (https://www.youtube.com/watch?v=omrY53kbVoA). On seeing the suggested syntax it was clear that clang-format would face some new challenges. (which might be exciting to work on)

This review is to add the basic infrastructure for Carbon as a potential clang-format language, to begin building that infrastructure and to fix a couple of Annotator issues which caused problems even with the simple language examples, namely "spaces around trailing return arrows and an additional space between type and colon in variable declarations"

I'm mainly submitting this to gauge interest from the team, and to see if others feel this might be something that we are interested in pursuing. (its also a good way to learn about Carbon.)
