externally_visible_p wasn't the correct predicate to use (even if it
worked), instead we should use DECL_EXTERNAL || TREE_PUBLIC.

PR ipa/94947
* tree-ssa-structalias.c (refered_from_nonlocal_fn): Use
DECL_EXTERNAL || TREE_PUBLIC instead of externally_visible.
(refered_from_nonlocal_var): Likewise.
(ipa_pta_execute): Likewise.
