It is highly unlikely we will switch compilers away from gcc -- we have 
enough problems just supporting multiple gcc versions.

That said, you could join the effort to get LLVM to compile under the 
kernel.  Here is a meta-bug for that: 
http://llvm.org/bugs/show_bug.cgi?id=4068

It is a moot question until LLVM can actually build a bootable kernel :)
