ir3: allow shared srcs for ldc.k
This works just fine and opens up a lot more opportunities for early
preamble. Note that I haven't seen actual cases where the index is large
enough to need a register but verified in computerator that it works.

The regressions in NOPs/MOVs seem to be cases of bad luck in
RA/scheduling. I looked at a couple of cases and the main shader is
essentially the same before RA. It's a bit unfortunate the differences
in the preamble can have such an impact on the main shader...

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
-------

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.
