Thanks @spatel @nemanjai  for your comments. So it should be a common-sense that we should not add TTI/TLI hook inside Reassociate Pass which was already kindly pointed out by @lebedev.ri .  I have learned this now ^_^. 
I will investigate all the suggested places to do the reversal (DAGCombine,  other PPC specific pass or CGP) later.
