Log:

	PR ipa/65475
	* ipa-devirt.c: Include demangle.h
	(odr_type_d): Add field rtti_broken.
	(odr_subtypes_equivalent_p): Do not require name to match.
	(compare_virtual_tables): Fix typo; if type already has ODR violation,
	bypass the tests; be ready for function referneces in vtables that are
	not DECL_VIRTUAL; make warnings to be OPT_Wodr.
	(warn_odr): Give up for nameless types.
	(warn_types_mismatch): Report mismatch in mangled names;
	report mismatch in anonymous namespaces; look into component types to
	give useful error; report when mismatch is dragged in from other ODR
	type.
	(odr_types_equivalent_p): Match types for being polymorphic; avoid
	duplicated diagnostics.
	(add_type_duplicate): Reorder checks so more informative ones come
	first; fix typo; do not output "the extra base is defined here" when
	we did not warn.
	(BINFO_N_BASE_BINFOS): Relax sanity check.
