@phosek With this patch as-is, we end up not building the runtimes at all because `install-runtimes` isn't executed when we run `ninja -C build`. I *think* that's because `install-runtimes` is not added to the `ALL` target in CMake. Is that voluntary or is it an oversight?

Also, @tsellar, do you want the LLVM releases to be built using the just-built Clang, or the system compiler? IMO it makes sense to use the bootstrapping build, but if we want to build the Phase 1 runtimes using the system compiler, we could use two CMake invocations, one rooted at `<monorepo>/llvm` and one rooted at `<monorepo>/runtimes`. This patch assumes that we want to bootstrap Clang and build the runtimes with it at each phase.
