[PATCH] D53189: [SCEV] Avoid redundant computations when doing AddRec merge

I expect compile time impact to be zero for majority of cases. It should only affect corner cases at which we reach limit depth during simplifications. For them, depending on simplifications complexity, we save `O(N)` time simplifying. I don't think it will really be observable on anything other than corner-cases.
