Printing "no pattern" as `_` isn't ideal, but better than crashing, and HIR pretty-printing already has plenty of imperfections. The added `f2` and `f6` examples are ones that triggered the crash. Note that some of the added examples are printed badly, e.g. `fn(, ...)`. The next commit will fix those. Fixes #139633.
