This emits SADD_SAT/SSUB_SAT generic intrinsics for the SSE saturated math intrinsics.
I'm still working on the llvm sibling patch (auto upgrade etc.) as there's a number of things that need unravelling. If people are interested in getting this committed quicker I could include minimal llvm side commit changes (GCCBuiltin and fast-isel tests) in the meantime.
