Qiu Chaofan e59e06d663 [DAGCombiner] Require ninf for division estimation ...

Current implementation of division estimation isn't correct for some
cases like 1.0/0.0 (result is nan, not expected inf).

And this change exposes a potential infinite loop: we use
isConstOrConstSplatFP in combineRepeatedFPDivisors to look up if the
divisor is some constant. But it doesn't work after legalized on some
platforms. This patch restricts the method to act before LegalDAG.
