Alyssa Rosenzweig a1885b2a35 panfrost/nir: Add nir_lower_blend pass
This new lowering pass implements the OpenGL ES blend pipeline in
shaders, applicable to hardware lacking full-featured blending hardware
(including Midgard/Bifrost and vc4). This pass is run on a fragment
shader, rewriting the store to a blended version, loading in the
framebuffer destination color and constant color via intrinsics as
necessary. This pass is sufficient for OpenGL ES 2.0 and is verified to
pass dEQP's blend tests. MIN/MAX modes are included and tested as well.
That said, at present it has the following limitations:

 - MRT is not supported (ES3).
 - sRGB support is missing (ES3).
 - Extended blending is not yet ported from GLSL IR lowering (ES3.2)
 - Dual-source blending is not supported. (N/A)
 - Logic ops are not supported. (N/A)

v2: Fix code conventions (per Ian Romanick's feedback). Implement color
masks.

This pass should be in common nir/ space, but due to non-technical
reasons, for now it's in Panfrost space. In the future, depending if
other drivers need some of the functionality, we can move this back to
src/compiler/nir space.

Other repositories are likely forks, and code found there is not supported.


Build & install
---------------

You can find more information in our documentation (`docs/install.html
<https://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.html <https://mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install


Support

appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.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.
