[PATCH] Tune TTI getMaxInterleaveFactor for POWER8

[hfinkel at anl.gov]

Thanks for working on this, but I don't quite understand the logic (stacking the latency of the two pipelines seems odd to me). How did you tune this?

Would the same logic apply to the `P7`?

Regardless, we'll need a test case (it would go in test/Transforms/LoopVectorize/PowerPC).
