LGTM

We could probably clean up the alignment handling in this pass now that the src and dest alignment of memcpy are separate.



================
Comment at: llvm/lib/Transforms/Scalar/MemCpyOptimizer.cpp:804
       if (I.mayThrow())
         return false;
     }
----------------
Not really related to this patch, but is mayThrow actually the right check?  Do we need willreturn instead?
