nir/algebraic: Lower CS derivatives to zero when no group defined
In compute shaders if no derivative group is defined, the derivatives
will always be zero. Specified in NV_compute_shader_derivatives.
To make the check more convenient, add a "info" local variable to the
generated code so we can refer to it in the Python rules. (Jason)
