sanopt: Avoid crash on anonymous parameter [PR93436]
Here we crash when using -fsanitize=address -fdump-tree-sanopt because
the dumping code uses IDENTIFIER_POINTER on a null DECL_NAME. Instead,
we can print "<anonymous>" in such a case. Or we could avoid printing
that diagnostic altogether.

* sanopt.c (sanitize_rewrite_addressable_params): Avoid crash on
null DECL_NAME.
