Alyssa Rosenzweig 4cdd85517d nir: Add intrinsics for multisampling on AGX
sample_mask_agx maps to the AGX instruction used to write out a sample mask.

api_sample_mask_agx is a system value that returns the value of glSampleMask
(or its Vulkan equivalent), used to lower glSampleMask (etc).
This is distinct from sample_mask_in, which we map to the hardware thing and
AND with this as a lowering.

sample_positions_agx is a system value returning the sample positions in a
packed fixed-point format matching the hardware register, used to lower
gl_SamplePositions.

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

.. 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.
