Qiu Chaofan 0c4c55c8ff [DAGCombiner] Improve division estimation of floating points.
Current implementation of estimating divisions loses precision since it
estimates reciprocal first and does multiplication.  This patch is to re-order
arithmetic operations in the last iteration in DAGCombiner to improve the
accuracy.
