Fix MPIU_Allreduce overflow check

The reduction can be done in int64 only if the Op handle is built-in,
otherwise a user-defined Op may not be able to handle dtype=MPIU_INT64.

Fix MPIU_Allreduce overflow check

The reduction can be done in int64 only if the Op handle is built-in,
otherwise a user-defined Op may not be able to handle dtype=MPIU_INT64.
From all the built-in Ops, only MPI_SUM and MPI_PROD can overflow.
