Sorry, but this test doesn't cover the situation mentioned here. It's
completely valid for a texture buffer to have a buffer object larger than 2^27B
bound to it. The issue mentioned here was that the size field in the surface
state object for buffers wasn't clamped to 2^27B as mentioned in the
texture_buffer spec.  More information about these surface state objects can be
found in the function, brw_emit_buffer_surface_state().
