Is this in the on-line docs somewhere?

In these runs we don’t care about the lit tests or the unit tests, because they are OS agnostic. We do this by specifying the compiler, lldb, and test flavor (static testcase + os, dynamic library testcase loaded by an OS image, dynamic library testcase loaded by an OS image running the OS’ debug stub).
