I re-wrote your implementation of IRR to use the Newton-Raphson Method. Now all
tests pass and the patch can be checked-in. 
My implementation was inspired by the Commons-Math's NewtonSolver:
https://svn.apache.org/repos/asf/commons/proper/math/tags/MATH_2_1/src/main/java/org/apache/commons/math/analysis/solvers/NewtonSolver.java

Applied in r1044370
