I'd suggest to put it in struct pipe_index_buffer.
The argument is that the index buffer needs to be prepared
specifically for the primitive restart enable setting:
1. If the index buffer has no restart indices, using primitive restart
will have no effect
2. If the index buffer has restart indices, not using primitive
restart will cause out-of-bounds accesses or weird rendering results
Also, the index size is there too, so there is no question of what
happens if the primitive restart index doesn't fit in the index size.
Currently the Mesa state tracker binds the index buffer for every draw
call, and thus would be unaffected (but it should stop doing that).
