Jelena Pjesivac-Grbovic 3740640711 Modifying MPI_Gather in tuned module:
- adding linear algorithm with synchronization for gather.
  This algorithm prevents congestion at root process, but introduces 
  synchronization (serializes non-root processes, but allows messages 
  to arrive from two processes at the same time).  
  It performed better than binomial and linear algorithms for large message, 
  and intermediate and large communicator sizes.
- Updating MPI_Gather decision function to reflect performance results
  from MX.  I will perform more measurements though - so this one can 
  change.

This commit was SVN r15165.
