I'm working on adding all the intrinsics we haven't implemented yet. Here's sinh, cosh, and tanh.
Sinh/cosh are implemented in the same commit because they forward to the same backing function (because the identities used only differ by a plus or minus).
-- v5: vkd3d-shader/hlsl: Implement tanh. vkd3d-shader/hlsl: Implement hyperbolic sin and cos.
