spirv: Use a simpler and more correct implementaiton of tanh() The new implementation is more correct because it clamps the incoming value to 10 to avoid floating-point overflow. It also uses a much reduced version of the formula which only requires 1 exp() rather than 2. This fixes all of the dEQP-VK.glsl.builtin.precision.tanh.* tests.
