Yes, llvm-gcc is bootstrapped (so it is compiled with llvm).

That could be a large task. I succeeded building a kernel with llvm a
while ago, but it didn't boot (neither did an UML kernel). You should
have very good knowledge of how the kernel works to find out what is
wrong. This is one place the tool I suggested could come in handy ;)

Maybe bugpoint. But you should discuss the design of the tool with Chris.
