[PATCH] D15230: [BranchFolding] Merge MMOs during tail merge

[Geoff Berry via llvm-commits]

I don't think that is correct.  If you look at the body of MachineInstr::mergeMemRefsWith() after Philip's change, it is only merging in the case where the MMO lists are the same.  I believe his intention was for you to refactor this change by making a similar change in mergeMemRefsWith() instead of in TryTailMergeBlocks()
