r600: update memory barrier operations
Note: the atomic host-mem-barrier tests assume that the atomic
buffer could be shared which is not how the r600 operates.

This change was tested on palm and cayman, with the exception
of the "atomic counter" tests, it fixes all the other cases:
spec/arb_shader_image_load_store/host-mem-barrier/.*: fail pass

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

.. 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
