Run time optimizations can be (are?) a very bad idea in a kernel, where very often the exact predictability of execution paths makes the difference between a working kernel and a misbehaving one.
Well, with Clang/LLVM you can compile the kernel straight to the target architecture with run time optimization turned off, as well as building what else you want, for instance your applications, with run time optimization turned on. Easy as customizing your Makefiles.
