While Michael did already answers your question, I wanted to inform you
about some recent efforts to introduce parallelism into the LLVM-IR. It
would make it feasible for clang to interpret (at least some) MPI calls,
though this is far ahead in the future.

If you are interested check out the discussion on the mailing list (look
for the [PIR] tag in the subject).

Cheers,
  Johannes
