brw: Add assembler support for DPAS

Browse Source 
Allow us to parse instructions in a form we currently generate

```
dpas.8x8(8)     g55<1>F         g47<1,1,0>F     g31<1,1,0>HF    g39<1,1,0>HF { align1 WE_all 1Q $4 };
```

Regions are not really needed, but this will be handled in a later patch
(that will also stop printing the regions).
