Wei Mi 7ba0bf14e8 [IndVars] Change the order to compute WidenAddRec in widenIVUse. ... When both WidenIV::getWideRecurrence and WidenIV::getExtendedOperandRecurrence return non-null but different WideAddRec, if getWideRecurrence is called before getExtendedOperandRecurrence, we won't bother to call getExtendedOperandRecurrence again. But As we know it is possible that after SCEV folding, we cannot prove the legality using the SCEVAddRecExpr returned by getWideRecurrence. Meanwhile if getExtendedOperandRecurrence returns non-null WideAddRec, we know for sure that it is legal to do widening for current instruction. So it is better to put getExtendedOperandRecurrence before getWideRecurrence, which will increase the chance of successful widening.
