Do this by removing the compatibility table and only using hard coded shaders when present. The hard coded shaders, along with the hard coding framework itself, can be dropped once the compiler is capable of compiling the hard coded shaders. In the meantime we don't want to risk regressing things that we know work because we temporarily can't test them. This restriction is being dropped now as the new compiler framework has been merged and we want to make use of it so it can be developed further.
