Caio Oliveira f8db53ccae brw: Fix comparison with unordered_mode when making baked dependency
The unordered mode stored in dependencies might be a bitmask and not
only a single mode.  In practice, only the "stronger" mode will stick.
Make sure that the code testing for the mode uses "&" instead of "==",
to avoid prevent some valid combinations to happen, e.g.

```
   // ...
   add(16)         g104<1>F        g94<1,1,0>F     g34<1,1,0>F     { align1 1H @7 $7.dst compacted };
```

which without the fix ends up as

```
   // ...
   sync nop(1)                     null<0,1,0>UB                   { align1 WE_all 1N F@7 };
   add(16)         g104<1>F        g94<1,1,0>F     g34<1,1,0>F     { align1 1H $7.dst compacted };
```

Enables two tests for the scoreboard pass that illustrate this case.

For measuring the effect, re-enabled the sync.nop accounting on total of
instructions and got the following results.

```
   Totals:
   Instrs: 322041261 -> 321748285 (-0.09%)
   Cycle count: 22864587567 -> 22863073741 (-0.01%)
   Max dispatch width: 7989040 -> 7989024 (-0.00%); split: +0.00%, -0.00%

   Totals from 88212 (9.78% of 902056) affected shaders:
   Instrs: 102282050 -> 101989074 (-0.29%)
   Cycle count: 12787629859 -> 12786116033 (-0.01%)
   Max dispatch width: 525336 -> 525320 (-0.00%); split: +0.01%, -0.01%
```

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
