1. adding top level configuration class and making shader and memory configuration

   components of this class.
2. clock memory pipeline no. subwarp times for each shader clock and increase
   rob-size for texture cache (trying to improve correlation, currently at 0.9218)
3. start to modify shader stats to add back features for visualizer (warp 
   divergence distribution kind of working again)

passing cuda 3.1 regression and ptxplus correlation tests
