e877ff61451c0b0d01d89a898422506f5ee5fea2 [InstCombine]Avoid introduction of unaligned mem access
InstCombine is able to transform mem transfer instrinsic to alone store or store/load pair.
It might result in generation of unaligned atomic load/store which later in backend
will be transformed to libcall. It is not an evident gain and it is better to keep intrinsic as is
and handle it at backend.
