Get rid of attempt to adaptively use Cholesky for inverting SPD matrices in matrix_inverse. Cholesky is not enough faster than PartialPivLU in Eigen to be worth the extra pass over the data to check for symmetry, even for relatively large matrices. For (n=2k) SPD matrices Cholesky does give ~5% speedup over LU, but for other matrix types we see an equivalent slowdown.
