[PATCH] D46010: [AArch64] Improve cost of vector division by constant

I tired this patch on Exynos and the performance of SPEC CPU2000 was virtually neutral, even if slightly negative overall in the integer score.  Perhaps the defaults costs are too optimistic about the relative difference between multiply and add?
