Implement hyperbolic function support for ESSL 3.00

Emulating arc hyperbolic functions is required on HLSL, where they do
not exist natively. For this, BuiltInFunctionEmulator is split into GLSL
and HLSL subclasses. The GLSL subclass handles the pre-existing built-in
emulation implemented for working around OSX bugs, and the HLSL subclass
handles emulating asinh, acosh and atanh on HLSL.
