get the sm optimized allreduce working for all but user defined
...
operations. Added to the reduction operations a set of reduction
functions that take 2 input buffers and one output buffer to avoid
some extra memory copies. These can't be used with user defined
operations. The intel c collective suite passes both original, and
new (new, not the user defined operations).
