    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.
