You could look at this example:
https://github.com/azat/clang/commit/6914e463518c2b4dd5403a957727e4b1d7bc7399

In short you should add next lines into lib/StaticAnalyzer/Checkers/Checkers.td:
def ReactorChecker : Checker<"Reactor">,
  HelpText<"Reactor">,
  DescFile<"ReactorChecker.cpp">;

And don't forget to add you module into CMakeLists.txt
