support log1p and expm1 jet Currently, it is not possible to accurately evaluate the derivative of d/dx log(1 + x) under all circumstances and significant deviations from the actual derivative d/dx log1p(x) can occur. This changeset introduces the necessary Jet overload and its inverse, expm1. Change-Id: Ifcf88f6d684f61ba86bbe49f0d551b703f34ad0d
