[Mesa-dev] [PATCH 08/10] i965/meta: Assert fast clears and rep clears never overlap

[Ben Widawsky]

There is nothing wrong with the code today, but as one modifies the code it
turns out to be not too difficult to mess up the code, and this easy assertion
should catch such driver implementation failures quickly.
