Instead of building compiler-rt alongside clang, we reuse the clang repack logic to put compiler-rts in place when building clang stage2 (which requires the profiling runtime). The repack logic is unified to handle all platforms as well, and now that compiler-rt is not built in clang, we also need to copy everything that is not lib/* from the compiler-rt artifacts, so we now also ensure that they're not diverging between those compiler-rt artifacts (except for darwin libs, which need to be unified into universal libraries). And as a bonus, we can also cross-build the mac clang toolchains with the stage1 clang and the clang runtime for the target platform.
