Sameer Agarwal 39b7cbaa5d Use absl hash containers for graph algorithms 
This reduces pre-processor time when finding an
ordering automatically substantially.

Before:

ComputeStableSchurOrdering
                                        Delta   Cumulative
              CreateHessianGraph :    0.50324      0.50324
                     Preordering :    0.00692      0.51017
            StableIndependentSet :    0.26341      0.77358
         ConstantParameterBlocks :    0.00095      0.77453
                           Total :    0.23978      1.01431

After:

ComputeStableSchurOrdering
                                        Delta   Cumulative
              CreateHessianGraph :    0.17183      0.17183
                     Preordering :    0.00226      0.17409
            StableIndependentSet :    0.12510      0.29919
