Alyssa Rosenzweig 151aa19c21 ttn: Set nir->info.separate_shader
TGSI has no legitimate[1] notion of linked shaders, which means tgsi_to_nir
should conservatively assume everything all shaders are separable. This requires
setting nir->info.separate_shader to warn drivers that shader CSOs might be
mixed and matched. Otherwise, the driver might enable optimizations that
are invalid for separate shaders, causing issues when the shaders are
later treated as separable.

This will fix varying linking with u_blitter's shaders on Panfrost (Bifrost and
older), when util_blitter_clear is used with Panfrost.

[1] There was a TGSI property added recently to forward
nir->info.separate_shader up to virglrenderer, but it's not actually used for
anything in virglrenderer and I am still struggling to understand what the use
case would be. My gut says we should revert b634030542 ("tgsi: Add
SEPARABLE_PROGRAM property"), but I'm not interested in fighting that yak right
now. Notably, the u_blitter and hud shaders are separable but are not marked
with this property.

Source
------

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://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja 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
mailing lists: `mesa-dev\@lists.freedesktop.org
<https://lists.freedesktop.org/mailman/listinfo/mesa-dev>`_
