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

* 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.

finish_aliases_1.
Jan, could you please have a look?
Thanks.
