      // 1) We inline the 'foo' call, so blocks now only contain HLoadClass instructions.
      // 2) We then run the select_generator pass, which cannot change the
      //    if/else because blocks contain instructions.
      // 3) We run GVN which will remove the HLoadClass instructions in the blocks.
      // 4) At code generation, we are in the unlikely situation that a diamond shape
      //    contains no instruction (usually removed by select_generator). This used
      //    to trip the ARM code generators.
