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.

Using the bootstrap build seems fine with me.  Is the phase1 runtime build used in phase2 or phase3 or is it just discarded?
