anv: Add compute only divergent atomics fusion optimization for Blender
Blender uses atomic operations as part of its virtual shadow mapping
implementation. Virtual shadow mapping page tagging in compute shaders
benefits from divergent atomics fusion, while fragment shaders doing the
atomic raster step in general have worse performance with this
optimization turned on.
Thus, an option is added to only apply divergent atomics fusion to compute
shaders in ANV, and this option is enabled for Blender.

Initial support for divergent atomics fusion optimization in ANV was added
in https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/40631.

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
