I don't think that LLVM contains an auto paralleliser at this time (not for SIMD, nor for multiple threads). Anyway, the above is an example of what I mentioned earlier (in the quoted text at the top of this message), since it's of course perfectly possible to also write multi-threaded versions using FPC.
