Rhys Perry fac813dc61 spirv: don't split memory barriers
If the SPIR-V had a shared+image memory barrier, we would emit two NIR
barriers: a shared barrier and an image barrier.

Unlike a single barrier, two barriers allows transformations such as:

intrinsic image_deref_store (ssa_27, ssa_33, ssa_34, ssa_32, ssa_25) (1)
intrinsic memory_barrier_shared () ()
intrinsic memory_barrier_image () ()
intrinsic store_shared (ssa_35, ssa_24) (0, 1, 4, 0)
->
intrinsic memory_barrier_shared () ()
intrinsic store_shared (ssa_35, ssa_24) (0, 1, 4, 0)
intrinsic image_deref_store (ssa_27, ssa_33, ssa_34, ssa_32, ssa_25) (1)
intrinsic memory_barrier_image () ()

This commit fixes two dEQP-VK.memory_model.* CTS tests with ACO.

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


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 `Freenode's #dri-devel
<irc://chat.freenode.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>`_


Bug reports
-----------

If you think something isn't working properly, please file a bug report
