Sameer Agarwal 83f70e5c02 Remove unnecessary memory allocations when using SuiteSparse. 
1. Add SuiteSparse::CreateDenseVectorView
2. Replace calls to SuiteSparse::CreateDenseVector with
   SuiteSparse::CreateDenseVectorView.
2. Replace NULL with nullptr in suitesparse.cc and
   dynamic_sparse_normal_cholesky_solver.cc

Sameer Agarwal 29c21f5680 Add SparseCholesky 
SparseCholesky is an interface to sparse cholesky factorization
routines across sparse linear algebra libraries. Each sparse
linear algebra library is responsible for implementing its own
instance of this interface.

As a result the various places - SparseNormalCholeskySolver,
SparseSchurComplementSolver and VisibilityBasedPreconditioner
are significantly simplified.

Sameer Agarwal 64a20e7ce2 Remove dead code from CompressedRowSparseMatrix. 
SolveLowerTriangularInPlace
SolveLowerTriangularTransposeInPlace

were unused functions which can be removed.

Sameer Agarwal 5c2fd0526a Add DynamicSparseNormalCholeskySolver 
This code was currently buried under a bool inside SparseNormalCholeskySolver.
Pulling this out in its own solver makes the code simpler more readable
and more performant in the case of SuiteSparse.
