i965: add plumbing for ARB_transform_feedback_overflow_query.

When querying for transform feedback overflow on one or all of the
streams, store information about number of generated and written
primitives. Then check whether generated == written.

v2:
    - use only SO_PRIM_STORAGE_NEEDED, do not fallback to
      CL_INVOCATION_COUNT. (Kenneth)
