	Static object to trigger the constructor which overwrites the dispatch pointer.

Computes the negative log likelihood sum with the same semantics as the CPU implementation of RooBatchComputeInterface::reduceNLL(): zero-weight events are skipped, and evaluation problems are counted and accumulated into a "badness" value that the host can pack into a NaN for the error recovery in the minimizer.

The stats output has the layout [badness, nNonPositive, nNaN, nInfinite] and must be zero-initialized.
