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.
