Sameer Agarwal 8c155d51fa Speed up the application of robust loss functions.
Since we added special handling for the case for rho[2] < 0,
the bulk of CorrectJacobian is pointless in the common case.
So add a simple one dimensional loop which rescales the Jacobian.
This speeds up this method immensely.

The robustification of a Jacobian gets speeded up by > 50%.
