libjpeg-turbo

Evaluate ICS jpeg for updated upstream code

Registered by Tom Gall

The Android project has released Ice Cream Sandwich. The libjpeg code needs to be compared to the 2.x release of Android for changes that would require rework of the libjpeg-turbo android patches. Benchmarking will be done with both skia bench and tjbench.
