We also have support for asan, tsan:

We can also use scan-build (ccc-analyzer  and c++-analyzer).

I looked quickly at the clang-tidy docs and it looks interesting.  I see 
it is setup to use the compile_commands.json file.  Originally we looked 
at running iwyu using that file.  However, it became quickly evident 
that this would be a pain to do.  By using it as pre-compile command  we 
can capture its output as compiler warnings and report them on the 
dashboard.  In addition, it can be run in parallel by the build tool 
(make or ninja).  I will take a look at clang-tidy as it might fit into 
the iwyu setup we created in a similar way.
