Handle `_` properly in a couple of places.
Currently (PatKind::Wild` (i.e. `_`) gets turned by `lower_fn_params_to_names` into an empty identifier, which means it is printed incorrectly by HIR pretty printing. And likewise for `lower_fn_params_to_names`, which affects some error messages. This commit fixes them. This requires a slight tweak in a couple of places to continue using parameter numbers in some error messages. And it improves the output of `tests/ui/typeck/cyclic_type_ice.rs`: `/* _ */` is a better suggestion than `/* */`.
