| useful for reordering loops and fusing operators. ``kOpaque`` tells TVM not to not bother trying to fuse this operator. |

Let's drop reordering loops, TOpPattern is only used for operater fusion.
A typo: not to not bother

Updates the tutorial and goes more in depth by using a more substantial operator than simple element-wise addition.
Instead we follow how PR #7334 and PR #7722 added cumulative product and addition operators.
