Pierre-Eric Pelloux-Prayer 064b477536 mesa/st: always use base_serialized_nir for draw 
f2f640f35 introduces base variants, so we get 2 NIR shaders:
glsl-to-nir -> base_serialized_nir
            -> serialized_nir

Then, depending on who is using the shader the right one would be picked:

* draw uses base_serialized_nir
* hw driver uses serialized_nir

ef0c9231a7 made sure that base wasn't used when the shader is loaded from
the cache because it's missing, so in this case, glsl-to-nir does:

glsl-to-nir -> from-cache -> serialized_nir

The problem is that if draw tries to use this shader it may fail, for
the same reason as the referenced commits were introduced: draw may not
be compatible with some NIR passes used by the driver.

To fix this we need to serialize both NIR shaders, and pick the right
one depending on the user.

Fixes: ef0c9231a7 ("mesa/st: don't use serialized_nir for cached shaders")

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

Support
-------

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `OFTC's #dri-devel
<irc://irc.oftc.net/dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
<https://dri.freedesktop.org/wiki/WhosWho/>`_.

The next best option is to ask your question in an email to the
