Note: not quite perfect, we should use type_size vfunc (in
compiler_options or nir_shader?) to determine how much we
increment num_inputs/outputs/uniforms. But we don't have
that yet, so let's at least fix things for the existing
users of these passes.

This is a common enough operation that it's nice to not have to think about
the arguments to foreach_list_typed every time.

The vertex shader lowering adds calculation for CLIPDIST, if needed
(ie. user-clip-planes), and the frag shader lowering adds conditional
kills based on CLIPDIST value (which should be treated as a normal
interpolated varying by the driver).
Note that this won't quite do the right thing in the face of MSAA plus
user-clip-planes, since all the samples would be killed or not (rather
than potentially only a portion of them). But it's better than no UCP
support at all for drivers that don't have this in hw.
