Jitse Niesen e7d809d434 Update eigenvalues() and operatorNorm() methods in MatrixBase.
* use SelfAdjointView instead of Eigen2's SelfAdjoint flag.
* add tests and documentation.
* allow eigenvalues() for non-selfadjoint matrices.
* they no longer depend only on SelfAdjointEigenSolver, so move them to
