Intel Commits More Mesa Performance Optimizations

Just days after landing some OpenGL performance tweaks, Intel's Eric Anholt has committed some more performance optimizations for the Intel i965 Mesa driver.

The two most recent commits are for adding VS instruction scheduling and enabling fast clears on non-8x4-aligned sizes. The vertex shader instruction scheduling only provides a minor boost in performance while the fast clears on non-aligned sizes causes around a 2.3% improvement.

The test-case Eric has been using as of late for Mesa driver performance tuning has been GLBenchmark 2.7. Interestingly, GLBenchmark 2.7 / GFXBench isn't a popular Linux game or tech demo, in fact it's hard to even obtain; it's more of a iOS / Android benchmarking app with no public Linux build.
