Allow a program that includes mpi.h to never use MPI. Before an error
was reported because MPI_Finalize was not called, but that was not fair
since MPI_Init() was never called (nor any other MPI function). Also
inserted a TODO comment in th MPI transformer about how to check that
the user has specified some upper bound on the number of MPI processes.
