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

[Steve Canon via llvm-commits]

Hence the "something like".  We should really just be able to pull and integer value out of APFloat (but again, outside the scope of this change).  Short-term, I think you can use V.convert(APFloat::IEEEdouble, ...) to get something that *can* be converted to double.
