      [Liftoff][ia32] Handle overflow in memory offset · a0e66bca
      Clemens Hammacher authored
      When generating a 64bit memory operation on ia32, we need to emit two
      operations, one at {offset+4}, one at {offset}. The computation
      {offset+4} can overflow, which is ok because
      1) it won't be used for code generation later, and
      2) the generated code will not be reached because the memory access is
         always out of bounds anyway.
