[PATCH] D18537: Don't vectorize loops when everything will be scalarized

Hal, I am not sure I understand the problem. Is the problem register pressure or the fact that store <8 x i32> is more expensive than 8 times store i32?

This looks like a problem with the PPC cost model that does not take into account the cost of scalarization.
