Jeff Squyres 23ab9e0277 A better solution to the previous commit -- RETAIN/RELEASE the MPI_Op

at the top-level MPI API function.  This allows two kinds of
scenarios:

1. MPI_Ireduce(..., op, ...);
   MPI_Op_free(op);
   MPI_Wait(...);

For the non-blocking collectives that we're someday planning -- to
make them analogous to non-blocking point-to-point stuff.

2. Thread 1:
   MPI_Reduce(..., op, ...);
   Thread 2:
   MPI_Op_free(op);

Granted, for #2 to occur would tread a fine line between a correct and
erroneous MPI program, but it is possible (as long as the Op_free was
*after* MPI_reduce() had started to execute).  It's more realistic
with case #1, where the Op_free() could be executed in the same thread
or a different thread.

This commit was SVN r7870.
