Use ShaderCore functions to implement GLSL.std.450 transcendentals
These ShaderCore implementations of transcendental functions are
identical to the current Reactor 'optimal' intrinsics. These were
already used by Subzero before, but not by Reactor's LLVM backend.
This change will enable removing approximate implementations of
transcendental functions which are Vulkan-specific, from the Reactor
side. Only full-precision reference implementations will be left.
