Job Noorman 893d3caf7b tu: use nir_opt_varyings_bulk for linking
Replace the use of nir_link_opt_varyings/nir_compact_varyings for
linking with the new nir_opt_varyings linker using the
nir_opt_varyings_bulk helper.

This moves all the NIR lowering up to nir_lower_io (tu_lower_nir) to the
pre-linking stage since nir_opt_varyings expects lowered IO.

This repository lives at https://gitlab.freedesktop.org/mesa/mesa.
Other repositories are likely forks, and code found there is not supported.


Build & install
---------------

You can find more information in our documentation (`docs/install.rst
<https://docs.mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ meson setup build
  $ ninja -C build/
  $ sudo ninja -C build/ install
