Folks,

I have recently stumbled on the following bizarre comment in 
InstCombinePass::run :
     // FIXME: The AliasAnalysis is not yet supported in the new pass 
manager
with subsequent nullptr instead of AliasAnalysis proper.

Is there any reason on why we do not pass an actual AliasAnalisys 
instead of that nullptr?
Here is patch that does this: https://reviews.llvm.org/D41203

regards,
   Fedor.
