Description
Work on double exp integrals and recent fast math work in gcc indicates that sinh(tanh(x)), cosh(tanh(x)), sinh(atanh(x)), and cosh(atanh(x)). I'm not interested in optimizing but in accuracy.

Research direction
No file, test, or entry point is named. Start by locating the existing special-function implementations and their accuracy tests, then determine how sinh(tanh(x)), cosh(tanh(x)), sinh(atanh(x)), and cosh(atanh(x)) should fit the library. Done means the requested functions are implemented and their numerical accuracy is covered.
