Reverted replication for HPL with Dimensional from r19370 back to r19362.
Reverted replication for HPL with Dimensional from r19370 back to r19362.

The changes in r19370 did not increase (decreased, more likely)
the performance when running on 64 nodes on a Cray XE,
while resulting in less elegant code.

Other than replication, r19370 also removed comments with suggestions on
how to replicate the sub-row used in the last computation in panelSolve().
Those comments are still out because they are not essential.
