r600g: Request DWORD aligned vertex buffers.
The spec says that the offsets in the vertex-fetch instructions need to be
byte-aligned and makes no specification with regard to the required alignment
of the offset and stride in the vertex resource constant register.
However, testing indicates that all three values need to be DWORD aligned.
