Matches the getArithmeticReductionCost / getExtendedReductionCost calls.

This will be necessary to correct recognize fast/nnan fmax/fmul reductions which can avoid nan handling - which will allow us to remove the fmax/fmin special case in X86TTIImpl::getMinMaxCost and use getIntrinsicInstrCost like we do for integer reductions (rG63c3895327839ba5b57f5b99ec9e888abf976ac6 <https://reviews.llvm.org/rG63c3895327839ba5b57f5b99ec9e888abf976ac6>).
