started fix of SVD solver that did not compute a least square solution
the fix is not complete yet as it seems the solution does not really gives the
smallest possible residuals. See for example the commented out parts of
testMath320A in SingularValueSolverTest.

Prevent NaN to occur for singular matrices
...
Numerical inaccuracies in the underlying eigendecomposition could induce
very small negative eigenvalues, so the square root produced NaNs. The
eigenvalues really cannot be negative, so it is safe to replace the negative
ones by 0.
There are remaining problems with singular matrices:
- the singular vectors also contain NaNs
- the solver does not really work in least square sense and
complain about singular matrices
