Ideas for things to do:
-- more projects (compiler-rt's asan/ubsan/msan/tsan, lldb)
+- more projects (lldb, check- targets for compiler-rt's asan/ubsan/msan/tsan)
- once there are more projects, have an llvm_enable_projects arg, modeled
after llvm_targets_to_build in the GN build
- a check-all build target that runs test of all projects
