    When folding memory operands, preserve existing MachineMemOperands. · a9f4d928

    This comes into play with patchpoint, which can fold multiple
    operands. Since the patchpoint is already treated as a call, the
    machine mem operands won't affect anything, and there's nothing to
    test. But we still want to do the right thing here to be sure that our
    MIs obey the rules.
