[PATCH] D13994: [SimplifyLibCalls] Optimization for pow(x, n) where n is some constant

David,
I see that all the optimizations for various math related functions is done in SimplifyLibCalls. So I guess SimplifyLibCalls should be the place to do it.
Did you have a particular reason why this expansion should be done in CodeGenPrep?
