Jelena Pjesivac-Grbovic 627533fe4a Adding segmented ring algorithm for Allreduce for commutative operations. ...

Algorithm allows user to specify the segment size to be used for computation/communication overlap.
The additional memory requirement for the algorithm is 2 x segment size.
It performed well for (really) large message sizes over MX and it passed intel Allreduce_c and Allreduce_loc_c tests.

This commit was SVN r13832.
