[PATCH] D111596: [SelectionDAG] Bail out of mergeTruncStores when not optimizing

I see similar checks sprinkled around DAGCombiner, so I guess this is ok too. Not sure if it is possible to do this at a higher level and remove those checks though.

But shouldn't this change the codegen for a reduced example of https://llvm.org/PR51827 ? Or is there some other `optnone` check that hides this one?
