--llvm-root <DIR> Path to the root of the LLVM monorepo. By default, we try
to figure it out based on the current working directory.
--build-dir <DIR> The directory to use for building the library. By default,
this is '<llvm-root>/build/<builder>'.
--osx-roots <DIR> Path to pre-downloaded macOS dylibs. By default, we download
them from Green Dragon. This is only relevant at all when
running back-deployment testing if one wants to override
the old dylibs we use to run the tests with different ones.
