Alyssa Rosenzweig 61dc9201a1 brw: constant fold before texture lowering
This ensures we don't need dynamic stuff. Noticed when debugging weird
regressions around the mcs lowering. ARL:

total instructions in shared programs: 19857061 -> 19854964 (-0.01%)
instructions in affected programs: 91768 -> 89671 (-2.29%)
helped: 154
HURT: 0

Instructions are helped.

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://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
-------

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.
