Fold the following case on IR InstCombine pass. This patch includes the new test cases for this optimization

  bitreverse(logic_op(x, bitreverse(y))) -> logic_op(bitreverse(x), y)
  bitreverse(logic_op(bitreverse(x), y)) -> logic_op(x, bitreverse(y))
  bitreverse(logic_op(bitreverse(x), bitreverse(y))) -> logic_op(x, y) with multi-use
