The test-suite [1][2] runs clang.  If you have an LLVM command-line flag to enable your
pass, you can use `-mllvm -your-flag` to pass your flag through clang.

There is some quickstart documentation on running LNT [3].  Have a look at the `--help`
for the `runtest` command to see how to customize which flags are passed down to clang
invocations.

Hope that helps!
