Did you forget to update the change? I'll run it against the failing chrome tests after. CFI-icall presents a <=1% performance regression for chrome so it would be hard to pick up a difference. From my past look at it, most of the regression appeared to because of cfi-icall checks at every malloc/free (because we override their implementations and require a function pointer call.)
