I might be missing some context here, but to address a very similar problem I have introduced an environment variable LIT_FILTER.
So if you want to run the test blah.test, you could run

$ env LIT_FILTER=blah.test ninja check-clang

I have found that much easier than trying to invoke clang directly.
