Speed up DenseSparseMatrix::SquareColumnNorm.

Because we store the matrix as row major matrix, the
obvious Eigen expression performs rather poorly. A straight
c++ loop speeds things up considerably.

Also replace use of matrix() with direct use of m_.

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.

Please see ceres-solver.org for more information.
