Marek Olšák fa5e07d5f7 ac/nir/tess: write TCS patch outputs to memory as vec4 stores at the end
This moves per-patch output VMEM stores to the end of the shader where they
execute only once. They are skipped if the whole workgroup discards
all patches.

If tcs_vertices_out == 1, per-patch output VMEM stores use the same lanes
as per-vertex output VMEM stores, which are aligned to 4 or 8 lanes to get
cached bandwidth for the stores.

Previously, per-patch outputs were stored to memory for every store_output
intrinsic in TCS.

Additionally, LDS is no longer allocated for per-patch outputs that are only
written and read by invocation 0, or they are written by all invocations
but not read, and don't have indirect indexing. This reduces LDS usage and
LDS traffic.

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

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.
