New Revision: 168954

URL: http://llvm.org/viewvc/llvm-project?rev=168954&view=rev
Log:
SciMark2-C: Rebalance iteration counts.

 - The different loops run in very different times, so try to pick values that
   roughly balance out to run the loops for the same duration (and roughly match
   the iteration counts that would have been used before).

 - Also, add support for SMALL_PROBLEM_SIZE.
