Mesa's Loop Analysis & Range Propagation Passes

Besides the atomic mode-setting for virtual KMS drivers, another X.Org Google Summer of Code project this summer was developing a range analysis pass and other optimization passes for Mesa as part of benefiting NIR.

Thomas Helland who was doing this work on loop analysis, LCSSA, and range propagation was able to mostly finish his work this summer. The work, however, has not yet been merged to mainline Mesa.

Currently this summer worth of work for Mesa can be found via his GitHub repository with more information on the project being found from this mailing list post by the student.
