Subject: [PATCH] [Doc] update the usage of opt with mem2reg pass in tutorial
 (#76282)

The current command will raise an error:

> The `opt -passname` syntax for the new pass manager is not supported,
please use `opt -passes=<pipeline>` (or the `-p` alias for a more
concise version).

Update the usage now.
