I've run another reghunt, which revealed that the 4.8 regression was
caused by this patch:

2012-05-23  Jan Hubicka  <jh@suse.cz>

       * tree.h (alias_diag_flags): Remove.
       (alias_pair): Remove emitted_diags.
       (finish_aliases_1, finish_aliases_2, remove_unreachable_alias_pairs,
       symbol_alias_set_t, symbol_alias_set_destroy,
       symbol_alias_set_contains, propagate_aliases_backward): Remove.
       * toplev.c (compile_file): Do not call finish_aliases_2
       * cgraphunit.c (cgraph_process_new_functions): Do not call
finish_aliases_1.
       (handle_alias_pairs): Output diagnostics about aliases to externals.
       (assemble_thunks_and_aliases): Use do_assemble_alias.
       (output_weakrefs): Likewise.
       (finalize_compilation_unit): Do not call finish_aliases_1.
       * ipa.c (symtab_remove_unreachable_nodes): De not call
remove_unreachable_alias_pairs.
       * varasm.c (do_assemble_alias): Export.
       (symbol_alias_set_create, symbol_alias_set_destroy,
symbol_alias_set_contains,
       symbol_alias_set_insert, propagate_aliases_forward,
propagate_aliases_backward,
       propagate_aliases_backward, trivially_visible_alias,
trivially_defined_alias,
       remove_unreachable_alias_pairs, finish_aliases_1, finish_aliases_2, 
       assemble_alias): Remove.
       * output.h (do_assemble_alias): Declare.
       * varpool.c (varpool_remove_unreferenced_decls): Do not call
finish_aliases_1.

Jan, could you please have a look?

Thanks.
