Makes sense overall. However in the future I'm looking to move away from the home-baked LTO pipeline in favor of giving it to the linker. That allows me to set up libraries as a part of the target toolchain in the driver. I guess for that I'll just need to forward `-mllvm` to the internal clang invocation.
