No test for miptrees with DRI modifiers

We currently have a bug in i965 related to modifiers. If the driver imports a tiled bo with a pitch >= 2^15 bytes, the driver will "retile" it to linear during miptree creation. I'll be sending out a fix for this soon.
As far as I'm aware, there isn't a framework that can be used to test this issue. We should have a test to prevent a similar issue from occuring again.
