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%)
