I have noticed that for auto-fu incremental re-builds, the compiler_rt build is 
missing the dependency on the just-built clang, so it doesn't get re-built if a 
new clang is made. Maybe this is contributing to what you're seeing?

Still sounds painful :(

I wonder how much disk space would be eaten up by saving every build always?
