Kenneth Graunke 765d74eebe brw: Set nir->info.{min,max}_subgroup_size in brw_nir_apply_key
This records the actual SIMD width we selected for the shader, in
all cases except fragment shaders, where we don't know it yet.

MR 37258 notes that "Backends can update [these fields] when they make
new decisions about the subgroup size" - which is what we now do.

Note that nir->info.api_subgroup_size may be different than min/max
subgroup size on Vulkan prior to SPV1.6/VK_EXT_subgroup_size_control,
so we do not alter that.

======================================================


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://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
