So all of these reference the __intrinsic_atomic_max functions. Do
those ned to be fixed up too? Specifically,

   add_function("__intrinsic_atomic_max",
                _atomic_intrinsic2(buffer_atomics_supported,
                                   glsl_type::uint_type,
                                   ir_intrinsic_generic_atomic_max),
                _atomic_intrinsic2(buffer_atomics_supported,
                                   glsl_type::int_type,
                                   ir_intrinsic_generic_atomic_max),
                _atomic_counter_intrinsic1(shader_atomic_counter_ops,
                                           ir_intrinsic_atomic_counter_max),
                NULL);

I believe the latter one needs to have its availability function
adjusted to be a||b.
