This series does a few cleanups to ISL so that it can actually handle multisampled HiZ correctly. When Chad and I first discussed HiZ, we thought it would all work out easy as ISL already had all the required code. We were correct that it had all the required code but wrong about the easy part. It turns out that there were some troublesome asserts and the choose_tiling and choose_msaa_layout paths weren't 100% HiZ friendly at least not when mutlisampling gets involved.
This little series cleans things up a bit and gets multisampled HiZ working. In the end, I'm very happy with these changes as I think they're almost all good changes even without HiZ. This series can replace patch 02/12 of Nanley's recent HiZ series.
