Move the DIS benchmarks up a directory and update hardcoded paths

Note that this repo does not attempt to keep a copy of the original
DIS benchmark distributions. UNC real-time has another repo for that.

+ * This source code is the completely correct source code based on 
+ * the example codes provided by Atlantic Aerospace Division, Titan 
+ * Systems Corporation, 2000.
+ * 
+ * If you just compile and generate the executables from this source

+ * understanding of this stressmark, it is strongly suggested that you
